T. Masuda et al., LINEAR AND NONLINEAR OPERATIONS OF OPTICALLY ADDRESSED SPATIAL LIGHT MODULATORS USING ANTIFERROELECTRIC LIQUID-CRYSTAL, JPN J A P 2, 33(4A), 1994, pp. 120000523-120000525
A new spatial light modulator using antiferroelectric liquid crystal a
nd amorphous silicon photosensor is presented. This spatial light modu
lator realizes real-time optical information processing by applying hi
gh-frequency voltage to the device. By changing the driving frequency,
we have achieved both linear and nonlinear operations with a single d
evice.
