Abstract

PURPOSE: To obtain the apparatus of a small size which combines the reproduction and trnasmission of information images by using laser rays and imaging lens, etc.
CONSTITUTION: The image of the small area H in a hologram recording plate 1 is introduced to lens 23 by the semiconductor laser light source 22 of a hologram information reproducing head 2. Since the laser source 22 enters at an accurate angle, the reproduced light L1 becomes diffracted light L2 which then enters the lens 23 correctly. If there is no lens 23, the image becomes large like Im but the reduced image Io is formed by the action of the lens. An optaical fiber bundle 24 is led to this position and the image sensor 4. Since such hologram information reproducing head may be constituted to 1cm3 or under at the portions of the head, the head may be miniaturized and since the optical fiber bundle 24 is flexible, its relative positions with the image sensor 4, etc. may be set as desired.
