FIELD: optics.
SUBSTANCE: device has control driver, spatial phase filter, containing modulating medium, connected with driver, vertical and horizontal profiled transparent electrodes and electron members for controlling refractivity of modulating medium. Spatial phase modulator is divided to pixels. Any pixel is located at are of crossing of horizontal and vertical electrodes. Random field of phase delay values is formed in pixels of spatial phase modulator due to change in spatial and time changes in random field of refractivity of modulating matter.
EFFECT: improved reliability of operation; smaller sizes; increased brightness of information image onto screen.
