Product introduction:
Portable Ultra-Wide Spectrum on-site Material Evidence Search and Recording System can take forensic records of fingerprints and footprints on the wall, enlarge the details in document inspection, record the photographic material evidences to the maximum extent; real-time high-definition large screen search and observation, integrated design of light source objective filter system, RAW format without compression of 30 frames/second video, maximum. Degree recording material evidence is the most suitable material evidence searching and recording system for criminal science crime scene investigation. The system uses the world-patented electronic multiplier noise reduction large target photoelectric conversion components. Criminal investigation shooting does not need refrigeration noise reduction, photomultiplier tube enhancement which is easy to damage, and does not need to smear on the sensor surface to enhance the ultraviolet sensation. After the complex achromatic high-definition micro-range optical objective of ultra-wide spectrum, the light is directly refracted on the large target imager, after the electronic multiplier signal and electronic noise reduction processing, the image is full and no impetuous point, which realizes the output of the continuous image of the material evidence inspection system, so that the material evidence inspection can be carried out from" The era of single-frame real-time has stepped into the era of & quot; 15-30 frames per second, 1920*1080 definition per frame (8M information per frame) continuous image RAW uncompressed format recording & quot; using the world's most advanced electronic multiplier noise reduction, ultra-wide spectrum high-definition imaging components, image distortion-free, high definition, high sensitivity in all bands, system configuration. The 35mm achromatic ultraviolet optical objective has excellent high-definition imaging from ultraviolet to visible to infrared. It has the function of micro-distance photography, and can be used for large area search, footprint photography, fingerprint feature and file inspection in detail enlarged shooting; 1920*1080, 30 frames/second real-time image output, uncompressed RAW SSD solid-state disk. Video recording, one person operation, search, observation, shooting at the same time in real time; specially tailored for criminal science scene material evidence shooting, photoelectric integrated human nature design is the most practical and practical crime scene investigation and forensics video recording system with advanced image processing software, providing an advanced platform for the post-processing of material evidence images. Prospective ultra-wide spectrum material evidence recording system, electronic multiplier noise reduction technology to improve the sensitivity of full spectrum camera is the latest and most cutting-edge imaging technology after back-illuminated refrigeration CCD and multiplier tube CCD. The clarity of the system reaches 2 million pixels and the ultraviolet sensitivity is greatly improved. The image output of the system is more continuous. In the past, the image acquisition system was discontinuous by prolonging exposure time/refrigeration/noise reduction, and the cost is high. Most of the refrigeration cameras were used in astronomical observation. Biological research and other areas do not require high image continuity, while forensics in criminal investigation requires high real-time image. Continuous images are easy to search and discover and multi-angle real-time recording of material evidence.
Product parameters:
1. Spectral Response Range: 180-1100 NM
2. Electron multiplier noise reduction technology: using large target ultra-low illumination science-level imager, the electronic multiplier signal, at the same time, through multi-sampling noise reduction technology to separate noise, get clear images. No refrigeration noise reduction, no multiplier tube enhancement. Continuous high-definition ultraviolet images can be obtained.
3. Image processing: The main computer of the video recording system has image automatic processing keys. According to different video objects, the brightness/contrast/gamma value of the image can be adjusted automatically to improve the image quality from the source.
