Abstract

We have developed a real-time fingerprint sensor using a flat glass plate with hologram. Personal identification by fingerprint validation will be widely used to maintain security of a computer system because of its high reliability. Such real-time sensors must be distortion free, high contrast, compact, and insensitive to residual fingerprints. The conventional prism-type fingerprint sensors have problems with distortion compensation and compactness.
