US 2006/0133643 A1 · 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 the 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 the fluorescent radiation emitted by the regions of evidence. The 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.

Dependent claims

A method for detecting and analyzing forensic evidence, comprising:

digitally capturing a background fluorescence image of a suspected-evidence area;
exposing the suspected-evidence area to a pulse of ultraviolet radiation;
digitally capturing an evidence-exposing fluorescence image of the suspected-evidence area;
processing the background fluorescence image and the evidence-exposing fluorescence image to
create a composite evidence image;
analyzing the composite evidence image to determine one or more fluorescing wavelengths
emanating from a corresponding one or more evidence regions within the
suspected-evidence area;
