Paper Abstract

We discuss experimental measurements of both spatial and temporal optical transfer characteristics of an optically addressed spatial light modulator (OASLM). The device incorporates a hydrogenated amorphous silicon (a-Si:H) photodiode and a surface-stabilized ferroelectric liquid crystal (SSFLC) modulator. Although the switching of SSFLCs is essentially binary at the microscopic level, the OASLM is shown to have an analog optical transfer characteristic. This is believed to be the result of both spatial and temporal averaging.
