1. An apparatus, comprising:
- a light source comprising a plurality of coherent sources, each coherent source being configured to emit light of a different color than the remaining of the coherent sources;
a reconfigurable array of mirrors and MEMS actuators, each mirror being controlled by a corresponding one of the MEMS actuators that is able to translate the controlled mirror in a piston-like movement normal to the array; and
wherein the light source is configured to illuminate the mirrors with a time division color-multiplexed light beam; and
wherein the reconfigurable array is able to modulate a phase of a wavefront of the light beam in a spatially non-uniform and reconfigurable manner.

Abstract
A method forms an image with a reconfigurable array of mirrors. The method includes configuring the array by translating some of the mirrors such that distances of the mirrors of the array from a reference plane have a non-uniform spatial distribution. The method includes illuminating the configured array with a coherent light beam such that part of the light beam is reflected off the array and is projected on a planar viewing screen.
