FAKE DOCUMENT INCLUDING FAKE CURRENCY DETECTOR USING INTEGRATED TRANSMISSION AND REFLECTIVE SPECTRAL RESPONSE |
摘要 |
A currency genuineness detection system using plurality of opto-electronic sensors with both transmission and reflective (including fluorescence) properties of security documents is developed. Both detection sensing strategies utilize integrated response of the wide optical band sensed under UV visible along with optional near infra red light illumination. A security document is examined under static condition. A window signal signature is thus possible from photodetectors responses for various kinds of documents of different denominations, kinds and country of origin. A programmable technique for checking the genuineness of a security document is possible by feeding a unique code of the currency under examination.
