技术原理

该测速系统基于红外光电感应遮断测时原理工作。在测量区段内，系统核心为一套宽36厘米、高30厘米的大面积红外光电感应屏，屏内集成了高密度红外发射管阵列与对侧的高灵敏度光电接收管阵列，形成一道垂直于弹道轴线的不可见红外光探测幕墙。当弹头以15米/秒至2133米/秒的速度飞越感应屏时，弹体瞬间遮挡部分红外光束，导致对应光电接收管的光通量产生纳秒级下降，触发一个尖脉冲光电信号。系统内嵌的高精度数字计时器实时捕捉弹头进入感应屏至离开感应屏的时间间隔，结合弹头穿过感应屏的已知距离，由中央处理器根据基本运动学公式v = d/Δt实时解算出弹头穿过感应屏的平均速度，并在LCD液晶屏上即时显示。

整套测量流程为完全非接触式——红外光对弹头无任何物理作用力，弹道轴线无障碍物干扰，确保所测速度真实反映枪支与弹药在实际射击工况下的性能特征。系统支持500次连续射击数据的综合统计，通过主机按键即可查询最高速度、最低速度、平均速度、极端散布（ES）及标准偏差（SD）等关键统计学参数，为枪支性能一致性评估与弹药批次质量检验提供科学的数据分析工具。系统采用220V交流电供电，同时配备电池支持现场使用，信号接口为BNC接口，便于与示波器或其他数据采集设备联机使用。整机采用高度便携的一体化设计，在现场几分钟内即可完成组装，使用后亦可快速折叠收纳，完美适应野外犯罪现场或临时测试场地的机动勘查需求。为满足更全面的鉴定需求，系统可选配电子天平（用于称量弹头重量以精确计算枪口动能）、口径测量数码卡尺及专业护耳罩等附件。

Product Overview

The U.S. CED-M2 Projectile Velocity Measurement System — Infrared Photoelectric Sensing, 36×30cm Large-Area Detection Screen, 15-2133m/s Wide Velocity Range, 500-Shot Data Intelligent Statistics, Portable Projectile Muzzle Velocity & Kinetic Energy Analysis Platform (also referred to as the U.S. CED-M2 Projectile Velocity Measurement System or CED-M2 Infrared Photoelectric Chronograph) is a new-generation portable professional velocity measurement device specifically designed for criminal technical investigation, firearm performance identification, and crime scene shooting reconstruction. It constitutes a core ballistic velocity measurement device in the fields of criminal technical firearm examination, judicial forensic firearm performance testing, and public security and armed police weapon acceptance and training. This product is originally imported and distributed by Beijing Best United Technology Co., Ltd. Utilizing advanced infrared photoelectric sensing technology, it employs a large-area infrared photoelectric sensing screen measuring 36 cm in width and 30 cm in height to precisely capture projectiles passing through it in a non-contact manner. The velocity measurement range covers 15 m/s to 2133 m/s, capable of accurately measuring everything from low-velocity special-purpose projectiles to the vast majority of standard rifle ammunition. The system features a built-in intelligent data statistics function that automatically processes continuous shooting data. With the press of a button on the main unit, key values such as maximum velocity, minimum velocity, average velocity, and standard deviation can be easily queried, calculated, and displayed. It can continuously record and comprehensively calculate data for up to 500 consecutive shots, providing a scientific basis for evaluating firearm performance consistency. The entire system adopts a highly portable, integrated design, being lightweight and easy to install. Users can complete on-site assembly within minutes and quickly fold and store it after use, taking up minimal space. It is also equipped with battery support, perfectly adapting to the mobile investigation needs of various field or temporary crime scene setups. The product is perfectly suited for various professional scenarios, including projectile velocity measurement and shooting distance inference in firearm-related crime scene reconstruction, statutory performance testing of involved firearms in forensic laboratories, muzzle velocity and kinetic energy assessment during weapon acceptance and training for public security and armed police, and ballistic research in scientific institutions. It fundamentally resolves the operational pain points of traditional contact-based chronometry methods, such as copper wire and tin foil targets, which suffer from frequent target surface replacement due to projectile impact, disturbance to the ballistic trajectory affecting measurement accuracy, and the inability to accommodate continuous measurement of high-rate-of-fire automatic weapons. It provides criminal technical examiners and weapon testing personnel with "infrared photoelectric non-contact high precision, ultra-wide velocity range for all ammunition types, 500-shot data intelligent statistical analysis, and portable battery dual-mode power for rapid on-site deployment" professional-grade projectile muzzle velocity and kinetic energy quantitative analysis capability. It is a critical core piece of criminal technical equipment for firearm-related crime scene reconstruction, statutory firearm performance identification, and scientific evaluation of weapon training.

Technical Principle

This velocity measurement system operates based on the principle of infrared photoelectric sensing interruption chronometry. Within the measurement section, the core of the system is a large-area infrared photoelectric sensing screen measuring 36 cm in width and 30 cm in height. The screen integrates a high-density array of infrared emitting tubes and a corresponding array of high-sensitivity photoelectric receiving tubes on the opposite side, forming an invisible infrared light detection curtain wall perpendicular to the ballistic axis. When a projectile flies through the sensing screen at a velocity of 15 m/s to 2133 m/s, the projectile body momentarily occludes some of the infrared beams. This causes a nanosecond-scale decrease in the luminous flux received by the corresponding photoelectric receiving tubes, triggering a sharp pulsed photoelectric signal. The system's embedded high-precision digital timer captures the time interval from the moment the projectile enters the sensing screen to the moment it exits it in real time. Combining this with the known distance the projectile travels through the sensing screen, the central processor calculates the average velocity of the projectile passing through the screen in real time using the basic kinematic formula v = d/Δt, and instantly displays it on the LCD screen.

The entire measurement process is completely non-contact—the infrared light exerts no physical force on the projectile, and the ballistic axis is free of any obstacle interference, ensuring that the measured velocity truly reflects the performance characteristics of the firearm and ammunition under actual firing conditions. The system supports the comprehensive statistical analysis of data from 500 consecutive shots. With the press of a button on the main unit, key statistical parameters such as maximum velocity, minimum velocity, average velocity, extreme spread (ES), and standard deviation (SD) can be queried. This provides a scientific data analysis tool for evaluating firearm performance consistency and ammunition batch quality inspection. The system is powered by 220V AC power, while also being equipped with a battery to support on-site use. The signal interface is a BNC interface, facilitating connection to an oscilloscope or other data acquisition equipment. The entire unit adopts a highly portable, integrated design, allowing for on-site assembly within minutes and quick folding and storage after use. It perfectly adapts to the mobile investigation needs of field crime scenes or temporary test sites. To meet more comprehensive identification needs, the system can be optionally equipped with accessories such as an electronic balance (for weighing projectile mass to precisely calculate muzzle kinetic energy), a digital caliper for caliber measurement, and professional ear protectors.

Core Functions and Compliance Operational Value

Infrared Photoelectric Non-Contact Wide-Range Velocity Measurement and Full Ammunition Type Coverage, Providing a Precise Muzzle Velocity Data Foundation for Statutory Firearm Performance Identification and Crime Scene Reconstruction
The system employs a large-area infrared photoelectric sensing screen to precisely capture projectiles in a non-contact manner. The velocity measurement range covers 15 m/s to 2133 m/s—accurately measurable from low-velocity riot control projectiles and injection gun projectiles to the vast majority of standard pistol, rifle, and submachine gun ammunition. The non-contact infrared photoelectric measurement principle fundamentally eliminates the deficiencies of traditional contact-based chronometry methods, such as copper wire and tin foil targets, which require frequent consumable replacement after the target surface is perforated by projectiles, the minute disturbance to the ballistic trajectory caused by impact that affects measurement accuracy, and the inability to support continuous velocity measurement for automatic weapons. This ensures that every velocity measurement data point is objectively accurate and repeatably verifiable. This performance provides a quantitative testing method that withstands both procedural and scientific scrutiny for the statutory muzzle velocity testing of involved firearms in forensic firearm identification, inferring shooting distance and angle in crime scene reconstruction, conducting performance inspections of new firearms during weapon acceptance by public security and armed police, and evaluating shooter firing stability during training. The objectivity of the identification data fully meets the technical requirements for firearm and ammunition performance testing stipulated in the Provisions on the Performance Appraisal of Firearms and Ammunition Involved in Cases by Public Security Organs.

500-Shot Data Intelligent Statistics and Multi-Parameter Automated Analysis, Supporting the Scientificization of Firearm Performance Consistency Evaluation and Ammunition Batch Quality Inspection
The system features a built-in intelligent data statistics function that can continuously record and comprehensively calculate data for up to 500 consecutive shots. With the press of a button on the main unit, key statistical parameters such as maximum velocity, minimum velocity, average velocity, extreme spread (ES), and standard deviation (SD) can be easily queried, calculated, and displayed. This intelligent statistical capability allows weapon testing personnel, during the acceptance of a new batch of ammunition, to quickly determine whether the ammunition's muzzle velocity consistency meets the required standards through the standard deviation value of the continuous shooting sample. In the performance identification of involved firearms, the statistical analysis of multiple-shot data can objectively evaluate the firearm's performance stability and state of wear. In shooter training, the velocity dispersion data can assess the shooter's firing stability. The generated statistical data can be directly used as a technical appendix to the expert report, providing objective data support that withstands statistical scientific scrutiny for the identification conclusion.

Portable Integrated Design, Dual-Mode Battery Power Supply, and Rapid Deployment, Meeting Full-Scene Mobile Velocity Measurement Needs from Laboratory to Field Crime Scenes
The entire system adopts a highly portable, integrated design, being lightweight and easy to install. Users can complete on-site assembly within minutes and quickly fold and store it after use, taking up minimal space. The system supports 220V AC power and is also equipped with a battery to support on-site use, allowing normal velocity measurement operations to be carried out at field crime scenes or temporary test sites without mains electricity. This portability and dual-mode power supply design allows the device to be flexibly deployed between fixed workstations in forensic laboratories, field shooting scenes, and open-air training grounds at public security and armed police bases. From the equipment mobility level, it comprehensively ensures the continuity and wide-area coverage capability of projectile velocity measurement work.

Compliant Application Scenarios

Projectile Velocity Measurement and Shooting Distance Inference Scenario in Firearm-Related Crime Scene Reconstruction
During the scene investigation of cases involving firearm-related intentional injury, fatal shootings, and suspected stray bullet incidents, criminal technical personnel use this velocity measurement system to conduct simulated shooting experiments at the crime scene or under laboratory conditions. Using the same model of firearm and the same batch of ammunition as those involved in the case, they precisely measure the projectile's muzzle velocity. Combined with ballistic analysis software, the forensic examiner can infer the shooting distance, reconstruct the ballistic trajectory, and analyze the kinetic energy attenuation pattern of the projectile at different distances based on the velocity measurement data. This provides critical scientific parameters for case reconstruction and injury potential assessment. The velocity measurement experiment process fully complies with the technical requirements of the Provisions on the Performance Appraisal of Firearms and Ammunition Involved in Cases by Public Security Organs. The obtained data is submitted to the court as a core technical appendix to the expert opinion.

Statutory Performance Testing of Involved Firearms and Ammunition Identification Scenario in Forensic Laboratories
When a forensic identification institution accepts a firearm identification commission for a firearm-related case, the forensic examiner uses this velocity measurement system under controlled laboratory conditions to perform statutory muzzle velocity testing and kinetic energy calculation on the involved firearm. Based on this, they determine whether the firearm meets the firearm determination criteria stipulated in the "Forensic Science Criteria for the Lethality of Firearms." Simultaneously, batch performance testing is conducted on the involved ammunition to assess whether its muzzle velocity consistency meets the factory technical specifications. This provides scientifically verifiable identification data for the court to accurately determine the nature of the involved firearm and the performance of the ammunition.

Public Security and Armed Police Weapon Acceptance, Training Evaluation, and Scientific Research Institution Ballistic Research Scenarios
During the acceptance of newly issued firearms, the evaluation of ammunition effectiveness, and the assessment of shooter training in public security and armed police forces, training instructors use this velocity measurement system to perform quantitative muzzle velocity and kinetic energy testing on each batch of firearms and ammunition. The test data is incorporated into the equipment performance management archive. In the ballistic research laboratories of weapon development units and scientific research institutions, researchers use this system for the design improvement and performance research of firearms and ammunition, providing core velocity measurement equipment support for the construction of standard firearm and ammunition laboratories.

Core Technical Parameters

In terms of measurement principle, the system operates based on the infrared photoelectric sensing interruption chronometry method, with the measurement process being completely non-contact. The sensing screen dimensions are 36 cm (W) × 30 cm (H) , providing a large-area detection window to ensure reliable projectile capture. The velocity measurement range covers 15 m/s to 2133 m/s, accurately measurable from low-velocity special-purpose projectiles to the vast majority of standard rifle ammunition. For data display, an LCD screen provides instant display of the single-shot velocity. The data statistics function can comprehensively calculate data for 500 consecutive shots, supporting the query and calculation of key statistical parameters such as maximum velocity, minimum velocity, average velocity, and standard deviation. For power supply, it supports 220V AC power and is equipped with a battery to support mobile on-site use. The signal interface is a BNC interface, facilitating connection for integrated use. In terms of physical characteristics, the entire system adopts a highly portable, integrated design, being lightweight and easy to install. On-site assembly can be completed within minutes, and the system can be quickly folded and stored after use. Optional accessories include an electronic balance (for weighing projectile mass), a digital caliper for caliber measurement, and professional ear protectors.

Compliant Field Application Cases

A fatal stray bullet incident occurred in a city where a victim was struck and killed by a bullet while on their own balcony. During the scene investigation, the public security organ preliminarily determined that the bullet might have originated from an illegal hunting site several hundred meters away. Criminal technical personnel brought this U.S. CED-M2 Projectile Velocity Measurement System to the crime scene. Using a hunting rifle of the same model as the involved firearm and the same batch of ammunition, they conducted simulated shooting experiments to precisely measure the projectile muzzle velocity. The velocity measurement system stably recorded the projectile muzzle velocity data over multiple repeated experiments. Based on this data, the forensic examiner, using ballistic analysis software, calculated the kinetic energy attenuation pattern of the projectile at different distances and inferred the spatial relationship between the shooting distance and the victim's injury location. This provided crucial scientific data support for identifying the suspect and determining the nature of the case. The velocity measurement experiment process fully complied with the technical requirements of the Provisions on the Performance Appraisal of Firearms and Ammunition Involved in Cases by Public Security Organs. The obtained data was submitted to the court as a core technical appendix to the expert opinion and was lawfully admitted during court cross-examination.

During the annual acceptance of police weapons and equipment, a provincial public security department needed to conduct performance testing on a newly procured batch of police pistols and their accompanying ammunition. Weapon testing personnel used this velocity measurement system to perform individual muzzle velocity tests on randomly sampled firearms and ammunition. Each firearm was fired 10 consecutive times. The system automatically calculated and displayed the maximum velocity, minimum velocity, average velocity, and standard deviation for each group. Based on the standard deviation values, the testing personnel evaluated the ammunition's muzzle velocity consistency and the firearm's performance stability. All test data was incorporated into the equipment acceptance archive. The muzzle velocity performance indicators of this batch of firearms and ammunition all met the technical standards of the procurement contract, successfully passed acceptance, and were issued to various grassroots units.
