Method and system for wide-area ultraviolet detection of forensic evidence
Abstract:
The present invention comprises a method for detecting and analyzing forensic evidence. A digital image is taken of background radiation from a suspected-evidence area suspected to contain evidence. The suspected-evidence area is exposed to a high-intensity pulse of ultraviolet radiation. Another digital image is taken of fluorescence within the exposed suspected-evidence area. The digital images are processed to create a composite digital image showing regions of evidence. The composite digital image is analyzed to determine the wavelength of fluorescent radiation emitted by the regions of evidence. Composite evidence image and the analysis results are displayed. The present invention also comprises a forensic evidence detection and analysis system that includes a digital camera, an ultraviolet light source, a computer and display, and a computer program installed on the computer.
