<p>The invention concerns a method of forming and reproducing a three-dimensional image of an object suitable for use in photography and television. A device has been developed for implementing the proposed method using standard means, as well as a modification of this device which can be used with television. The technical solution which has been developed permits the use of incoherent radiation in the formation and reproduction of a three-dimensional image, in particular, a white light source, and ensures very high resolution (not less than 10 lines per mm) and good contrast (not less than 100). In addition, it considerably reduces the bandwidth needed to transmit the image of an interference pattern using a television channel compared to the bandwidth needed to transmit a holographic image. In order to use the proposed method with television, use is made of a standard transmission TV camera adapted to the present invention. The camera's objective lens has a wide field of view, and a first interference structure comprising two optically connected interference filters is mounted along the beam path in front of the photo-sensitive element. A standard receiving TV tube, fitted with another interference structure between the screen of the receiving TV tube and the viewer, is used to reproduce the three-dimensional image. The source of reproduction radiation is the screen of the receiver TV tube which also serves as the carrier of the image of the interference pattern.</p> |
