Use of narrow-band-pass filters to enhance detail in latent fingerprint photography by laser.
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. 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.
