1. A light modulator comprising:

  • a. elongated elements arranged in parallel wherein each element includes a light reflective planar surface; and

    b. a support structure coupled to the elongated elements to maintain a position of the elongated elements relative to each other and to enable movement of each elongated element between a first modulator configuration wherein the elongated elements act to reflect an incident light as a plane mirror, and a second modulator configuration wherein selected groups of elements are deflected and act to diffract the incident light along one or more of a plurality of diffraction planes, wherein the groups of elements are configured according to one of a plurality of selectable group configurations, each group configuration corresponding to one of the plurality of diffraction planes.
