Abstract: A projection system and method includes a light source configured to emit a light in response to an image data; a phase light modulator configured to receive the light from the light source and to apply a spatially-varying phase modulation on the light; and a controller configured to determine, for a frame of the image data, a plurality of phase configurations, respective ones of the plurality of phase configurations corresponding to solutions of a phase algorithm and representing the same image with a different modulation pattern, and provide a phase control signal to the phase light modulator, the phase control signal configured to cause the phase light modulator to modulate the plurality of phase configurations in a time-divisional manner within a time period of the frame, thereby to project a series of subframes within the time period.

Abstract: A system and method comprise a light source; a spatial light modulator including a substantially transparent material layer and a phase modulation layer; an imaging device configured to receive a light from the light source as reflected by the spatial light modulator, and to generate an image data; and a controller. The controller provides a phase-drive signal to the spatial light modulator and determines an attenuating wavefront of the substantially transparent material layer based on the image data.
