Classification: CPC G  B  Y | IPC G

Claim 5:
6. The system of claim 3 wherein each of the MEMS based diffractors comprises:
a piston layer suspended over the surface of the substrate by posts at corners thereof, the piston layer including an electrostatically deflectable piston and a number of flexures through which the piston is coupled to the posts;
the first reflective surface over a top surface of the piston; and
a faceplate suspended over the piston layer, the faceplate including the second reflective surface on a top surface of the faceplate, and an aperture through which the piston exposed,
wherein electrostatic deflection of the piston brings light reflected from the first reflective surface into interference with light reflected from the second reflective surface.
