Abstract:
A method and system for zonal switching for light steering to produce an image having high dynamic range is described. The system comprises: a light source for providing light along an optical path; a spatial light modulator for directing portions of the light to off-state and on-state light paths, thereby producing an image, the spatial light modulator having a plurality of illumination zones corresponding to the image; and a set of sequentially-arranged optical elements in the optical path for steering at least some of the light from a first subset of the plurality of illumination zones to a second subset of the plurality of illumination zones to increase the dynamic range of the image. The dwell time of the one or more sequentially arranged optical elements can be modified to steer light.
