Conventional methods of gathering forensic evidence at crime scenes are encumbered by difficulties that limit local law enforcement efforts to apprehend offenders and bring them to justice. Working with a local law-enforcement agency, Sandia National Laboratories has developed a prototype multispectral imaging system that can speed up the investigative search task and provide additional and more accurate evidence. The system, called the Criminalistics Light-imaging Unit (CLU), has demonstrated the capabilities of locating fluorescing evidence at crime scenes under normal lighting conditions and of imaging other types of evidence, such as untreated fingerprints, by direct white-light reflectance. CLU employs state of the art technology that provides for viewing and recording of the entire search process on videotape. This report describes the work performed by Sandia to design, build, evaluate, and commercialize CLU
