1. A light modulator comprising:

  • a micro-electromechanical optical phase shift device;

    a polarization displacement device that combines phase shifted polarization components of light reflected by the micro-electromechanical optical phase shift device;

    a polarizing beam splitter that analyzes the output of the polarization displacement device; and

    , a system of at least two lenses that focuses, by different amounts in perpendicular planes, analyzed light from the polarizing beam splitter.
