ABSTRACT:
Predetermined hologram images7a, 7bformed by three-dimensionally arranging a plurality of data items constituting data group information are read out from hologram devices6a, 6b, and an image correlation calculation between the hologram images7a, 7bis carried out by a Fourier transform optical system constituted by Fourier transform lenses8, 13and an optical address type SLM9, whereby a correlation value of data groups is detected by a photodetector14.
