During a recent installation of the VMD360 at the Pinellas County Sheriff’s Office in Largo, Florida we processed several pieces of fabric.
One of the pieces considered was a patch from a pair of polyester running shorts (see pic #1)
Using just the VMD process, the material was inspected and no obvious signs of fingerprints were discovered. We then examined the fabric utilizing an Alternate Light Source (ALS), the Polilight at 450nm, which revealed positive results for fingerprint ridge detail of searchable quality (see pic #2). This photograph was then enhanced (see pic #3).
