Annotation

The barrier filter used to date to photograph fingerprints by laser does not eliminate substrate luminescence that can reduce or destroy the value of the fingerprint.

Abstract

Use of a narrow-band-pass filter with an appropriate transmission spectrum can often isolate the desirable fingerprint luminescence and yield a better photograph of the print. (Author abstract)
