1. 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;
Using a processor (or computer) to perform the steps of:
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; and
displaying the composite evidence image and analysis results.
