PRODUCTION OF HOLOGRAM WHICH IS CORRECTED IN ABERRATION BY CURVILINEAR USE

摘要

PURPOSE: To correct the aberrations generated in the image formed by a hologram in the case of using of the hologram in the curved state for reproducing and imaging by putting a photosensitive material into the same curved state as a use state and interfering two luminous fluxes, thereby recording the hologram. ;CONSTITUTION: The light rays from a light source 1 and a light source 2 are interfered and the hologram is recorded on the photosensitive material 3. The photosensitive material 3 is constituted by sticking a photosensitive film onto a curved glass plate by using xylene as a curvature matching agent. The fresh photosensitive material is brought into tight contact with the hologram original plate obtd. in such a manner and is exposed, by which the reproduced hologram is produced. Illuminating light is preferably so set that the distribution of the incident angle of the illuminating light to the photosensitive material and the hologram original plate is equaled to the distribution of the incident angle of the one luminous flux at the time of recording of the hologram original plate.;COPYRIGHT: (C)1993,JPO&Japio
