Abstract

PURPOSE: To remarkably improve the recording density of information in a hologram recorder.
CONSTITUTION: In a hologram recorder, a phase modulation type liquid-crystal space light modulator 104 is set up in a reference wave optical path 102, and an amplitude modulation type liquid-crystal space light modulator 103 is set up in an object wave optical path 101. The phase modulation type liquid-crystal space light modulator 104 is used for generating a specified phase distribution and encoding a reference wave surface. On the other hand, the amplitude modulation type liquid-crystal space light modulator 103 is used for displaying an image to be recorded. Using the reference wave surface encoded at each image, plural images are superposed on an electro-optic material 105 and recorded. Since the encoded reference wave surfaces are orthogonalized with one another, a desired image alone is reproducible by selecting the reference wave surfaces. The maximum number of images recordable in pile is equal to a picture element number of the liquid crystal space light modulator being used, thus an amount of more than 104 is easily achieved.
