Information processing method and information processing system
摘要:
Predetermined hologram images 7a, 7b formed by three-dimensionally arranging a plurality of data items constituting data group information are read out from hologram devices 6a, 6b, and an image correlation calculation between the hologram images 7a, 7b is carried out by a Fourier transform optical system constituted by Fourier transform lenses 8, 13 and an optical address type SLM 9, whereby a correlation value of data groups is detected by a photodetector 14.
