At the request of the U.S. Army Office of the Provost Marshall General, the U.S. Army Land Warfare Laboratory performed a test and evaluation of the Coherent Optical Fingerprint Identification System (COFIDS). This system employs the techniques of optical holography to encode fingerprint details and store such information, with high data density, on miniature photographic films. Identification is performed by comparing fingerprints with the hologram using optical cross-correlation. The test, involving over 100 people of USALWL, was carefully designed and instrumented to provide complete statistics of performance. The evaluation indicates that the system provides a highly foolproof means of personnel identification. Equipment improvements are desirable to automatically compensate for fingerprint variability and to reduce the learning process required of users.
