Abstract:
1. A method of processing a fringe pattern from a Fabry-Perot interferometer, comprising: a. generating at least one portion of a circular fringe pattern with a Fabry-Perot interferometer responsive to at least one light signal incident thereupon, wherein said at least one portion of said circular fringe pattern is formed of light from said at least one light signal; b. imaging said at least one portion of said circular fringe pattern from said Fabry-Perot interferometer onto a digital micromirror device (DMD), wherein said digital micromirror device (DMD) comprises a plurality of micromirrors arranged in an array, wherein each micromirror of said plurality of micromirrors constitutes a pixel that can be rotationally positioned to a plurality of different pixel-mirror rotational states, and each pixel-mirror rotational state of said plurality of different pixel-mirror rotational states corresponds to a particular associated rotational position of said micromirror; c. processing said at least one portion of said circular fringe pattern, comprising:
