ABSTRACT:
The invention relates to stereoscopic video equipment and can be used to design stereoscopic TV sets and monitors with a possibility to observe stereo images both glasses-free and with use of passive glasses while keeping a possibility to observe monoscopic images. These possibilities are provided in the method and in the device by means of a light flux elliptical polarization modulator with polarization modulation parameters determined by inverse trigonometric functions such as arctg, arcctg, arccos and arcsin (or their combinations) from algebraic relations between squared amplitudes of image temporal scanning signals, that permits with help of spatially-periodic polarization selector to obtain the images of the left and the right views in the left and right observation areas.
