ABSTRACT:
A solid cylindrical recording medium is axially rotatable within a cavity in a transparent block, the medium and the cavity being complementary in shape. The medium and the block have substantially equal indexes of refraction whereby the medium does not refract light transmitted thereto through the block. Transmitted to the medium (through the block) is an object beam, representative of an image, and a reference beam, whereby the medium is exposed and a volume hologram of the image is recorded. A multiplicity of volume holograms of images may be recorded by rotating the medium with respect to the reference beam after each of a multiplicity of exposures.
