Annotation: A portable high-resolution electronic imaging system has been designed and built for recording laser or ultraviolet excited fluorescent marks at serious crime scenes; such a system can be used to detect and record physical marks such as fingerprints.
Abstract: A 2048 by 2048 Peltier-cooled CCD camera and PC-based image capture system contained in two flight cases forms the basis of the system. The captured images can be viewed at the scene to ensure recording quality and then returned to the laboratory for storage on magneto optical disks for hardcopy production or digital image processing. The camera system has been taken to crime scenes for evaluation and is now well into its operational testing. It is already clear that cutting exposure times from several minutes to seconds will save considerable time at a scene where many fluorescent marks have been found. The high sensitivity of the camera extends the range of imaging techniques that can be used at crime scenes. It will supplement rather than replace conventional photography to improve the detection of evidence. Photographs, figure, and 4 references (Author abstract modified)
