Dmd blazed grating
Webalso consists of an AR-coated gain chip, a fixed blazed grating and a rotational micromirror. The laser light emitted from the gain chip shines directly onto the blazed grating; the selected wavelength is diffracted to the micromirror and is then reflected and diffracted back into the gain chip. In comparison to the standard Littman WebExtending to Two Dimensional Gratings . Armed with the understanding of 1D grating diffraction we can extend this same understanding to two dimensions. We will restrict our …
