INFLUENCE OF ABERRATIONS OF OPTICS ON DENSITY OF RECORDING OF HOLOGRAPHIC INFORMATION

Abstract

The problems of holographic recording of information are analyzed. Traditionally developed memory systems were aimed at storing “cold data” - digitized arrays of long-term storage with rare accesses to them. When recording analog holograms for these purposes, an essential role is played by optical aberrations. The influence of aberrations is analyzed both in binary information recording and image recording schemes. The obtained estimates of the recording density of information even with a decreasing coefficient determined by aberrations indicate the impossibility of transmitting such holograms over the radio channel. To solve the problem of transmitting holographic information over a radio channel in augmented reality and holographic television devices, it is proposed to use a coding method close to the method of transmitting information on one side band, which is known in the radio range, expressed in the transfer of two arrays equivalent in volume to a conventional TV channel and the synthesis of holograms on the receiving end of a channel.
