PROCESS OF FORMATION AND RECONSTRUCTION OF VOLUMETRIC IMAGE AND DEVICE FOR ITS IMPLEMENTATION

摘要

FIELD: photography, television. SUBSTANCE: there was developed device for implementation of process with the use of standard means and its modifications as applied to television. Proposed technical decisions make it possible to use noncoherent radiation, specifically, source of white light when forming and reconstructing volumetric image and to ensure rather high resolution up to ten lines per mm as minimum and good contrast range not worse than 100. Requirements to width of band for transmission of image of interference picture over TV channel are also decreased sufficiently as compared with requirements to transmission of holographic image. For realization of process on television there is used standard TV camera updated in compliance with given invention for formation of volumetric image. Lens 12 in TV camera has large aperture at least over horizontal line and first interference filter 6 is placed ahead of light sensitive element in path of ray. Standard TV tube fitted with second interference filter 10 located between screen of receiving TV tube and observer is used for reconstruction of three-dimensional image. Screen 14 of receiving tube which functions simultaneously as image carrier of interference picture is source of reconstructing radiation. EFFECT: expanded application field, improved operational characteristics of device. 8 cl, 3 dwg øøø1
