HIGH-CONTRAST DISPLAY SYSTEM WITH SCANNED CONFORMAL GRATING DEVICE
First Claim
1. An improved projection system that includes a conformal grating electromechanical system (GEMS) device for forming an image on a medium, comprising:
- a) a light source providing illumination;
b) a linear array of conformal GEMS devices receiving the illumination;
c) an obstructing element for blocking a zeroth order reflected light beam from reaching the medium;
d) a cross-order filter, placed substantially near a Fourier plane of a lens system, for blocking a plurality of diffracted cross-order light beams from reaching the medium;
e) a scanning element for moving non-obstructed diffracted light beams relative to the medium; and
f) a controller for providing a data stream to the linear array of conformal GEMS devices.
