Abstract

PURPOSE: To eliminate the need for a compound-eye lens by providing a reproduction system and detector fixed-distance away from a hologram where light is separated by standard patterns.
CONSTITUTION: A standard pattern is arranged at position 9c to record an interference pattern of a signal wave from a spot light source passing through this standard pattern and a reference wave from a reference light source on a photosensitive material. Next, this standard pattern is replaced and the spot light source is moved so as to record an interference pattern in the same way. Hologram 10b obtained in this way is irradiated with light at wave surface 13 opposite to the reference wave used in recording, so that the conjugate pattern of the entire standard pattern will be reproduced at position 9c at the same time. Light relating to the reproduction of this image is separated next, causing the spectrum of each standard pattern to aposition corresponding to each spot light source in recording. Therefore, detector 15 is arranged at an adequate position, input pattern 14 is set at position 9c, and the output of detector 15 is compared, so that input pattern 14 can be discriminated from standard patterns without using a compound-eye lens.
