METHOD FOR RECORDING AND DISPLAYING OF THREE- DIMENSIONAL PICTURE OF OBJECT AND DEVICE FOR RECORDING AND DISPLAYING OF THREE-DIMENSIONAL PICTURE OF OBJECT Russian patent published in 1997 - IPC

FIELD: photography, TV equipment. SUBSTANCE: method involves illumination of object by light , generation of interference pattern, its recording and detection of three-dimensional position of light beams from object as well as detection of light beams using photodetector. During displaying method involves exposition of interference pattern to playback light and detection of beams which intensity, three-dimensional position and direction correspond to characteristics of beams which are detected during interference pattern recording. Set of such beams corresponds to three-dimensional picture of object. Recording of three-dimensional picture involves three-dimensional filtration of beams from different directions according to two independent angular coordinates using first pair of interference filters which are designed for running interference with dividing amplitudes. In addition three-dimensional positions and directions of beams from object are recorded by means of first pair of interference filters and by means of photodetector. During displaying three-dimensional picture of object exposition of interference pattern with light involves illumination of first pair of interference filters or second pair of interference filters which are designed for running interference with dividing amplitudes. Function of three- dimensional filtering of second pair of interference filters corresponds to function of three-dimensional filtering of first pair of interference filters. Scale of interference pattern which is provided by second pair of interference filters corresponds to scale of exposed interference pattern. Corresponding device has generating light source 1, three-dimensional picture generation unit 2, three- dimensional picture generation unit 3, first pair of interference filters 5, photodetector 6, displaying light source 7, interference pattern carrier 8, second pair of interference filters 9. EFFECT: increased functional capabilities. 10 cl, 3 dwg
