Document Type and Number:
WIPO Patent Application WO/2001/022190
Kind Code:
A1
Abstract:
Each of a plurality of items of data constituting data group information is three-dimensionally arranged to form predetermined hologram images (7a, 7b), which are read from hologram elements (6a, 6b), a computation of image correlation between these hologram images (7a, 7b) being made by Fourier transform optical system composed of Fourier transform lenses (8, 13) and optical address type SLM9, whereby the correlative value of the data group is detected by an optical detector (14).
