ABSTRACT:
An apparatus and a method for three-dimensional (3D) color televisions where the two simultaneously recorded static or movie pictures of a scene from two different directions are merged into one picture of a TV-receiver is disclosed. The pickups from two different directions are reproduced in different orientations of linear polarization of light such that when viewing through glasses with different polarization, each eye will receive the picture of each recording separately which will be perceived as a 3-D image. The different orientations of linear polarization are produced by subjecting the images from a first direction to an electric field which causes the light to become plane polarized according to the Kerr effect, while the electric field is switched off for the images from the second direction. Polarization is thus provided on alternate frames as light passes through a fiber optic medium which includes thin, transparent electrodes which are switched on and off in synchronization with the frame repetition rate.
