Abstract:
1. A device for modulating light comprising: an array of modulation elements each of which includes a reflective electrode and an at least partially reflective surface defining an interferometric cavity, wherein the reflective electrode is moveable relative to the at least partially reflective surface through a range of positions; and control circuitry connected to the array of modulation elements and configured to control each modulation element in the array, wherein the relative positions of the reflective electrode layer and the at least partially reflective surface causes each modulation element to exhibit an optical response to light, wherein the control circuitry is configured to control an amplitude of light delivered by the array, and wherein controlling the amplitude of light delivered by the array includes controlling a fraction of a scan during which a modulation element is activated.
