Abstract
We demonstrate and characterize the use of an optically addressed ferroelectric liquid crystal (FLC) spatial light modulator (SLM) as a spatial filter. The photosensor associated with the liquid crystal is a PIN photodiode made of hydrogenated amorphous silicon (a-Si:H). Both the amplitude and the phase of the reflection coefficient are observed to be modulated by the write beam. The filter function can be reconfigured at a submillisecond rate with incoherent illumination.
