Abstract

PURPOSE:To realize the linear plane scanning of reconstructed images easily and obtain the distortion-free reconstruction images of high resolutions by changing the spacing between holograms and a spot light source for diffused light or the incident angle of the incident luminous flux of the light source to the holograms in synchronization with the rotation of a hologram scanner. CONSTITUTION:A diffused light source 31 emits luminous fluxes toward a hologram cylinder 5, and it is possible to subject the reconstructed images to linear plane scanning on an imaging plane 4 by suitably moving the light source 31 in an optical axis direction in synchronization with the rotation of the cylinder 5 by way of a moving actuator 32 consisting of a voice coil or a linear motor. Or the incident angle of reconstructed light to a hologram disc 3 is changed by moving a light source 41 in the direction perpendicular to the optical axis by a moving actuator 32 in synchronization with the rotation of the disc 3. Thereby, the linear plane scanning of the reconstructed images is accomplished easily and the distortion-free reconstructed images of high resolutions are obtained.
