1. A modulator for modulating an incident light beam comprising:

  • a. a plurality of elongated, spaced-apart members formed parallel to one another and substantially in a first plane, wherein alternating members are in a first portion and remaining members are in a second portion;

    b. a gamma controller for displacing the plurality of elongated spaced-apart members to a bias plane, wherein the bias plane is parallel to the first plane; and

    c. a displacement controller for displacing the first portion of the spaced-apart members to the bias plane to reflect the incident light beam and to a second plane parallel to the bias plane to diffract the incident light beam.
