An optically addressed spatial light modulator based on a single-crystal silicon Schottky diode array photoreceptor and nematic liquid crystals with a high photosensitivity (better than 1μW/cm2) and input light intensity adaptation range (greater than 3 orders of magnitude) is demonstrated. This photosensitivity and intensity adaptation range is concurrent with a spatial resolution of 25 line pairs/mm, contrast ratios greater than 200:1, and response times less than 10 ms in a wide photosensing wavelength range of 400–1100 nm.
