    摘要: The disclosed spatial light modulator includes a pair of facing transparent electrodes, and a light-modulating layer and a photoconductive layer provided between the transparent electrodes In the spatial light modulator, the light-modulating layer has different optical states depending on an applied charge amount. Specifically, the light-modulating layer has: a first optical state when the applied charge amount is a first threshold charge amount or more; a second optical state when the applied charge amount is a second threshold charge amount or less; and a spatially uniform intermediate state between the first optical state and the second optical state depending on the applied charge amount. Also, a driving method for such a spatial light modulator is disclosed.

    摘要: A spatial light modulator having a photoconductor, a matrix of reflectors and a modulating layer is disclosed. The portions of the photoconductor in between the reflectors have a smaller photoconductivity than those portions under the reflectors. The reduced photoconductivity can be made, for example, by doping the photoconductor while using the reflectors as a mask or by illuminating the photoconductor with a light of 360 joules/cm.sup.2. The photoconductor in between the reflectors may be grooved, The photoconductor can be a superlattice photoconductor.
