Fingerprint sensor using fiber optic faceplate

This paper presents a new fingerprint sensor for automated fingerprint identification systems. This fingerprint sensor consists of alight source, a charge coupled device and fiber optic faceplates. Because of the fiber optic faceplates, this fingerprint sensor does not have the space for image formation that a lens has and thus can be miniaturized. The size of the prototype fingerprint sensor, which has a 12 mm by 18 mm fingerprint input face, is 48 mm by 72 mm by 44 mm. The verification performance is evaluated by using this prototype.
