ABSTRACT:
A spatial light modulation device, in which at least a photoconductor structure and a light modulator have a multilayer structure. In this spatial light modulation device, the photoconductor structure has a plurality of pixel portions and avalanche multiplication of charges generated by light incident on each of the pixel portions is performed therein and charges obtained as a result of the avalanche multiplication are stored in the pixel portions. Thus, this spatial light modulation device has high sensibility.
