    摘要： There is disclosed herein a liquid crystal spatial light modulator which is driven y an analog input voltage and which includes, among other components, a layer of liquid crystal material that changes the way in which it acts on light in response to predetermined changes in voltage across the layer, whereby to modulate the light so acted upon, and an arrangement for applying a light modulating voltage across the layer of liquid crystal material and for modulating the voltage during a given modulation period. This latter arrangement includes a non-linear capacitor and a voltage coupling scheme for changing the voltage across the capacitor during the modulation period in a way which changes the capacitance of the capacitor and thereby capacitively couples at least a part of the change in voltage across the capacitor to the layer of liquid crystal material.
