Application Introduction of Dual-Source Dual-View Item Security Inspection System in Criminal Investigation and Forensic Science Identification
This system is a specialized security inspection equipment for criminal technology, based on dual-source dual-view X-ray imaging and multi-energy material identification technology. Through synchronous scanning from vertical and horizontal directions, it completely solves the pain points of image overlap and occlusion of traditional single-view equipment. It can non-destructively obtain high-definition detailed images of inspected items, accurately distinguish organic substances, inorganic substances and mixtures, and intelligently highlight and mark dangerous goods such as explosives and drugs. It provides accurate, efficient and compliant technical support for criminal investigation, physical evidence preservation and forensic identification, and is a core tool for contraband interdiction and physical evidence analysis in the field of criminal investigation.
Core Application Scenarios and Forensic Identification Value
1. Contraband Interdiction in Correctional Facilities: Deployed in visiting rooms and logistics channels of prisons and detention centers, it conducts strict inspections on packages, clothing, food and other items sent into the correctional area, accurately intercepts contraband such as drugs, controlled knives and communication equipment components, and simultaneously retains high-definition security inspection images. These images serve as compliant evidence for handling violations and investigating cases, ensuring correctional security.
2. Investigation of Drug and Explosive-Related Cases: At public security checkpoints and logistics sorting centers, it quickly screens for drugs and explosives concealed in luggage and packages. Through its material identification function, it assists in judging the nature of suspicious powders and crystals, providing a basis for on-site rapid disposal and targeted extraction of physical evidence. During searches of case-related dens, it conducts rapid preliminary screening of seized luggage and items, locates key suspicious physical evidence, and improves investigation efficiency.
3. Auxiliary Analysis of Forensic Physical Evidence: For sealed case-related boxes and suspicious mail items that are not suitable for direct opening, it conducts non-destructive internal inspection, clearly presenting the type, quantity and distribution of internal items, and providing preliminary information for formulating laboratory opening and inspection plans. The retained high-definition images can be used as audio-visual evidence to assist in case reconstruction, investigative experiments and court cross-examination.
4. Professional Skill Training: Through the Threat Image Projection (TIP) function, it conducts synchronous skill training in actual security inspection work, improving the X-ray image interpretation ability of criminal investigation and forensic personnel, and ensuring the accuracy and standardization of physical evidence identification.
Typical Criminal Investigation Application Cases
- Interdiction of Drug-Related Logistics Cases: Deployed in a logistics sorting center, it accurately identified drugs hidden in packages, confirmed the nature of suspicious powders through the material identification function, locked the case-related packages, and provided core physical evidence and direction for case investigation.
- Interception of Contraband in Detention Centers: It seized controlled blades and micro communication components concealed in visiting packages. The high-definition images clearly showed the hiding position and item details, serving as compliant evidence for violation handling and preventing contraband from entering the correctional area.
- Non-Destructive Inspection of Case-Related Physical Evidence: It scanned the sealed case-related boxes, clarified the distribution of internal suspicious items, provided accurate guidance for laboratory opening and inspection, and avoided damage or contamination of evidence caused by blind opening.
