PURPOSE: To provide the optical beam shifter consisting of an artificial double refraction plate which decreases the loss of the light of optical space switches.
CONSTITUTION: This optical beam shifter is constituted by disposing two sheets of wedged-shaped transparent substrates 1-1, 1-2 opposite from each other and holding a liquid crystal layer 9 between the transparent substrates 1-1 and 1-2. The optical beam shifter is connected with the optical beam shifters to the rear surface of a matrix type deflection control element. Two sheets of the wedge-shaped transparent substrates are disposed opposite from each other and, therefore, the optical beam shifter with which matrix driving is possible and which is connected in multiple stages with the optical beam shifters holding the liquid crystal layers for shifting incident optical beams by a half cell by shifting the shifters by half cell each is obtd.
