Patent Images

1. Apparatus for projecting stereoscopic images, comprising:

  • a first polarizing splitting element configured to receive first image light energy and split the first image light energy received along a first primary path and along a first secondary path;

    a first reflector configured to receive one of first primary path of light energy and first secondary path of light energy and to reflect the one of first primary path of light energy and first secondary path of light energy toward a surface;

    a first rotator configured to receive one of first primary path of light energy and first secondary path of light energy and to rotate the one of first primary path of light energy and first secondary path of light energy;

    a second polarizing splitting element configured to receive second image light energy and split the second image light energy received along a second primary path and along a second secondary path;

    a second reflector configured to receive one of second primary path of light energy and second secondary path of light energy and to reflect the one of second primary path of light energy and second secondary path of light energy toward a surface; and

    a second rotator configured to receive one of second primary path of light energy and second secondary path of light energy and to rotate the one of second primary path of light energy and second secondary path of light energy.
