Abstract

This paper describes a technology for a compact spectrometer based on a 2D piezoelectric mirror and/or grating array. The piezoelectric mirror/grating array is composed of angularly movable, 2-D array of micromirrors/microgratings that is supported on piezoelectric cantilevers, and can be driven piezoelectrically with controllable tilt angle in both upward and downward directions. A large reflecting/diffractive surface is obtained through a combination of the small-sized mirrors/gratings that are surface-micromachined without fabrication difficulties associated with a large size mirror/grating.
