Bistable spatial light modulator using a ferroelectric liquid crystal.
A bistable spatial light modulator is developed by utilizing optical bistability of ferroelectric liquid-crystal molecule.Both positive and negative images are read out by changing the polarity of applied electric pulses. A binary image is stored for more than 2 h, and gray-level operation is also possible during the gradual decay after writing.
