OPTICAL INFORMATION PROCESSOR AND VERIFICATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide an optical information processor capable of executing a verification processing in a short period of time without increasing device cost and circuit scale. SOLUTION: The optical information processor for making information light 206 having image information about two-dimensionally arranged digital information interfere with reference light 205 and recording the pattern of the interference in a hologram disk 216 has a CMOS sensor 219 in which the information light 206 and reproduction light reproduced by emitting the reference light 205 to an area with the interference pattern recorded can be inputted and charge corresponding to input light is stored, and a verification processing part 10 for executing verification processing on the basis of information of first signal charge stored in the CMOS sensor 219 by the information light 206 and information of second signal charge stored in the CMOS sensor 219 by the reproduction light.
