Abstract

PURPOSE: To grasp the optical optimum conditions for obtaining holograms of good quality by concentrically developing and fixing a plurality of holograms having been exposed and recorded on the same dry plate.
CONSTITUTION: When a dry plate 1 is set with high accuracy in the specified position through the ON-OFF operations of a switch button by digital assignment and a shutter 6 is opened through a photo detecting window 4 after this, the stereoscopic images of different states are recorded by a double exposure method on the dry plate 1. Following to this, the dry plate 1 is two-dimensionally moved by driving DC motors 8 and 10 and recording is done by the similar operations under the conditions of the intensity comparison of the laser output, object light and reference light or exposure time differing from that of the previous time. By performing this operation plural times under varying conditions, a plurality of holography informations in always the same fixed observation position may be recorded on the same dry plate. Hence, if this dry plate is developed and fixed, the optical optimum conditions for obtaining the holograms of good quality are efficiently grasped.
