Abstract

We report a miniature mirror-tilt-insensitive (MTI) Fourier transform spectrometer. A large-vertical-displacement (LVD) MEMS mirror is used to generate large scan range for high spectral resolution. The LVD MEMS mirror is also reflective on both surfaces. The maximum tilting angle of the MEMS mirror is 1.7° for its entire 1-mm scan range. The combination of a corner-cube retroreflector and dual-reflective MEMS mirror has been used to compensate the mirror tilting successfully and resulted in high spectral resolution of 8.1 cm-1.
