FINGERPRINT OBSERVATION AND RECORDING SYSTEM

摘要

A system for observing and detecting evidence (A), including fingerprints. The system includes an attachment (20) for video camera (15) that allows a "live" fingerprint to be observed and recorded so that it may be compared with latent fingerprints that may be detected and recorded with the same system when the attachment (20) has been removed. The attachment (20) includes a beamsplitter (32) for directing light to a finger cradled for viewing by a video camera (15). When the attachment (20) is removed, the video camera (15) uses a pair of matched filters (40, 42), a source of noncoherent light (10), a light intensifier (44) to detect the wavelength-shifted luminescence from fluorescent substances. The system may be hand held and portable.
