Abstract
An optical deflector comprises a photo-conductive material having a temperature optical effect and formed with a propagation path for light which propagates in a predetermined direction, a heating and cooling member disposed on the surface of the light propagation path of the photo-conductive material and which effect heat generation operation for heating the photo-conductive material and endothermic operation for cooling the same to produce the distribution of refractive index corresponding to the temperature distribution formed by each operation, in the light propagation path, and a drive DC source to have the heating and cooling member effect the heat generation operation and endothermic operation.
