The spectrometer utilizes resonant mode vertical comb actuators as a variable-depth diffraction grating and a single photodetector to monitor the 0th order of the diffraction pattern. The spectrum of the source illuminating the gratings is computed by Fourier transforming the 0th order intensity as a function of the optical path difference. The vertical comb actuators have a travel range of 100 mu m under atmospheric pressure with 28V excitation, which yields a theoretical spectral resolution of 0.5nm in the visible and better than 5nm in the telecom wavelengths.pdfOpticsInstruments and instrumentationA MEMS based visible-NIR Fourier transform microspectrometer - art. no. 61860CConference proceedinghttps://doi.org/10.1117/12.664781238881100017N/ANOIR00525
