Abstract
A display device or a receiver device for use with coherent light. A controller applies phase shift values to a multi-region phase array at a frequency sufficiently higher than the flicker fusion rate of the human eye or other intended receiver in order to remove the perception of speckling artifacts which would otherwise appear due to the coherency of the light.
