ABSTRACT:
A hologram apparatus includes a light beam interfering section for allowing reference and signal light beams to interfere to form a hologram recording region; a reproducing section for allowing the reference light beam to be incident on the recording region and generating a reproduced light; an image sensor for detecting a hologram-reproduced image; a distortion determining section for detecting the distortion-detecting data from the hologram-reproduced image to determine a distortion of the hologram-reproduced image; a distortion corrector for correcting a distortion of the hologram-reproduced image; and a controller for correcting the distortion in accordance with a determined distortion.
