The handheld backscatter X-ray inspector (portable single-sided X-ray imaging equipment) is a core portable contraband detection device in the field of criminal investigation technology and forensic identification. Based on fly-point scanning backscatter imaging technology, it relies on the advantages of single-sided imaging, easy operation and low radiation, focusing on the rapid screening of concealed dangerous goods and contraband and the preliminary fixation of physical evidence in complex scenarios. It effectively solves the pain point that traditional detection equipment is difficult to adapt to complex positions such as wall-adjacent and vehicle-mounted locations, provides efficient and safe technical support for criminal investigation on-site inspection and forensic identification, and greatly improves the efficiency and accuracy of concealed physical evidence investigation.
The core characteristics of the equipment are accurately adapted to the needs of criminal investigation and forensic identification, providing comprehensive support for the upgrading of identification technology: single-sided imaging does not require a detector to be arranged on the back, enabling non-contact detection of difficult-to-penetrate double-sided positions such as wall secret compartments, vehicle interlayers and furniture interlayers, solving the problem of physical evidence investigation in complex scenes; it has high sensitivity in identifying low-density organic substances such as explosives and drugs, and can clearly distinguish organic substances from inorganic substances, providing intuitive basis for preliminary screening of contraband and classification of physical evidence, and assisting identification personnel in quickly locking core exhibits; the image is clear with distinguishable details, capable of identifying small traces, and combined with the design of one-key start-stop and no preheating, it can quickly complete on-site evidence collection and avoid damage to exhibits; the low-radiation design ensures the safety of operators, adapts to long-time on-site inspection, and complies with the safety specifications of forensic identification.
Combined with actual criminal investigation, two typical cases demonstrate its value: Case 1, in a vehicle drug hiding case, when the police inspected a suspicious vehicle, they used the equipment to scan the door and tire interlayers, and quickly identified the hidden drugs without disassembly. Through imaging, they clearly distinguished the drugs from vehicle components, quickly fixed the physical evidence, provided a preliminary screening basis for the qualitative analysis of the drug case, and improved the inspection efficiency. Case 2, in a burglary and drug hiding case, the police used the equipment to scan the on-site walls and furniture, found the concealed secret compartments and the drugs and stolen money hidden inside, broke through the limitations of traditional detection through single-sided imaging, accurately located the position of physical evidence, assisted identification personnel in completing the extraction and fixation of physical evidence, and promoted the detection of the case.
In summary, the equipment is suitable for core criminal investigation scenarios such as building inspection, vehicle security inspection, drug control and anti-smuggling. It effectively makes up for the deficiencies of traditional detection equipment, simplifies the on-site evidence collection process, provides reliable technical support for contraband screening and concealed physical evidence investigation, standardizes the evidence collection link of forensic identification, and is an indispensable portable concealed dangerous goods screening equipment in the field of criminal investigation and forensic identification.
