The Wide-Angle Footprint Investigation Light Source System is a specialized optical equipment for footprint discovery and extraction in the fields of criminal scene investigation and forensic identification. Adopting a combined design of a main lamp and a handheld auxiliary light source, the system relies on core technologies such as wide-angle uniform illumination, multi-band filtering and dual-zone dimming to solve the pain points of uneven illumination, difficult trace visualization and incomplete extraction of traditional light sources. It provides accurate optical support for footprint investigation, fixation, comparison and forensic identification, ensures the integrity and standardization of footprint evidence, and assists in case detection and judicial justice.
The core performance of the system is accurately adapted to the needs of criminal investigation and forensic identification: wide-angle uniform illumination can fully cover the investigation area, avoiding the omission of faint footprints due to local shadows; multi-band filtering and fluorescence enhancement functions can clearly visualize footprints treated with fluorescent reagents, as well as dust and faint footprints, improving trace recognition; the combined dual light sources and adjustable irradiation distance are suitable for different indoor and outdoor ground conditions, the main lamp is used for large-area on-site investigation, and the auxiliary light source is used for local detail supplementation, facilitating accurate positioning and extraction of footprints; dual-zone independent dimming can enhance trace contrast, ensure the clarity of footprint photography and recording, and provide high-quality image basis for footprint comparison and identity confirmation in subsequent forensic identification.
Combined with criminal investigation practice and forensic identification cases, its application value is prominent: Case 1, in the on-site investigation of a burglary case, faint dust footprints were left on the ground, which could not be clearly visualized by traditional light sources. With the wide-angle illumination of the system's main lamp and blue filter, complete footprints were quickly visualized and fixed, and details were supplemented by the auxiliary light source. The extracted footprint images were clear, providing key evidence for suspect footprint comparison and identity confirmation in forensic identification. Case 2, in the on-site investigation of an outdoor robbery case, mixed footprints were left on different grounds (soil, cement). The system distinguished different footprint levels by adjusting the irradiation angle and filtering mode, accurately extracted the suspect's crime footprints, and recorded trace details synchronously, providing reliable technical support for footprint feature analysis and crime process reconstruction in forensic identification.
In summary, the system is suitable for various footprint investigation scenarios such as criminal scenes and traffic accident scenes. It can efficiently discover, clearly visualize and standardize the fixation of various footprint traces, improve the efficiency of investigation and the quality of trace extraction, provide high-quality evidence support for footprint identification and trace comparison in forensic identification, standardize the investigation and identification process, and is an indispensable professional footprint investigation equipment in the fields of criminal investigation technology and forensic identification.
