Abstract

The holographic system for an optical memory is examined. A Fraunhofer hologram of an array object is recorded near the focal plane of a thick transforming lens. This hologram is read out with a spherical wave, and the intensity distribution in an image plane is theoretically calculated and experimentally measured. The concept of a traveling subaperture connected to a local recording of information in the hologram is verified.
