FIELD: physics, optics.
SUBSTANCE: infrared polarisation light filter is described, installed on an emitter of infrared sync signals of a device of stereoscopic image display. The device alternately displays the right and left images by the method of time separation using polarised light in one direction. Glasses include polarising plates arranged near in the right and left fields of view. On the front surfaces of polarising plates above each other there are opening/closing fields of view and liquid crystal cells that adjust inclination. A sync signal receiver is installed on the frame of the glasses and receives a polarised infrared light sync signal. Liquid crystal cells that open/close fields of view are actuated synchronously so that the right and left fields of view alternately open/close relative to the displayed light of the device of stereoscopic light display. Voltage is applied to liquid crystal cells that adjust inclination in accordance with the angle of inclination. A detector of the inclination angle is also installed on the frame. The angle of rotation of the light polarisation plane in liquid crystal cells that adjust inclination is regulated. Maximum screened condition is always maintained during closure of fields of view.
EFFECT: prevention of crosstalk.
