Development of an optical joint transform correlation system for fingerprint recognition

Yuji KobayashiHaruyoshi ToyodaCentral Research LaboratoryHamamatsu Photonics K.K.5000, Hirakuchi, HamakitaShizuoka 434-8601, JapanE-mail: kobayasi@crl.hpk.co.jp,toyoda@crl.hpk.co.jpAbstract. A compact joint transform correlator is designed and con-structed to test the properties of a practical application and is applied tofingerprint recognition. The system performance is evaluated on finger-print recognition accuracy under thermal conditions ranging from 0 to40°C and is found to provide a high level of identification and rapidprocessing abilities under actual environmental conditions.
