摘要：
By using a ferroelectric liquid crystal light valve having a hydrogenated amorphous silicon photoconductive layer, a spatial light modulator may be driven by a method comprising the sequential application of successive pulse voltages of selective amplitude, polarity and duration to cause the spatial light modulator to manifest a second threshold level suitable for application of the device in Boolean processing applications and Fourier image processing.
