title: Laser detection of latent fingerprints: preparation of fluorescent dusting powders and the feasibility of a portable system.
abstract: A simple procedure for the preparation of dusting powders with a variety of fluorescent colors is described. Such powders permit detection of latent prints by laser even when the surfaces holding the latent prints luminesce strongly. A possible portable laser detection system is also suggested.
