DEVELOPMENT AND INVESTIGATION OF ACOUSTIC-OPTIC DEVICES FOR TIME SYNTHESIZING FOURIE-HOLOGRAMS OF RADIO SIGNALS AND THEIR REPRODUCTION

By Georgy Arkadyevich Matevosov

Abstract

The work covers the acoustic-optic holographic memory devices. The aim is to develop and investigate the memory device with high speed and high density of the information recording. The analysis of holographic recording circuit with oncoming-scanning beams, analysis of acoustic-optic deflector with repeated diffraction and also the design of parameters in the heterodyne reproduction of radio signals from holograms have been given. The circuit engineering has been developed, the experimental investigation of acoustic-optic devices for synthesizing of the radio signal Fourie-holograms and their reproduction has been performed, the original circuit designs and radio-electronic equipment complex have been proposed. The organization of recording on the disc carrier and also the methods for designing diffraction efficiency of the applied holograms are used in the Moscow Research Institute of Instrument-Making and St.-Petersburg Institute of Aviation Instrument-Making. The speed and density of information recording are increased, the requirements to the following accuracy and disc rotation speed are decreased. Application field: television (of high definition), radio astronomy, information-computer complexesAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
