ABSTRACT:
A hologram recording plate, which has a plastic layer (a rosin derivative) that undergoes frost deformation by being acted upon by a solvent vapor, is set in a developing box supplied with a solvent vapor (cyclohexane) from a solvent vapor reservoir. The solvent vapor is exhausted from the developing box by a suction device. This is followed by subjecting the hologram recording plate to a high voltage from a high-voltage power supply and irradiating the plate with laser light, which represents a hologram to be formed, by opening a light shutter. This makes it possible to reduce the size of and to automate the hologram producing apparatus. The developing box and optical elements inclusive of a light source are secured to respective ones of individual carriers, and the carriers are provided so as to be free to be moved along an optical system aligning rail and fixed to the rail. A very simple and precise optical system can be constructed without using an optical bench or table having a vibration-proof structure.
