Abstract
A spectrometer employs multiple filters having complex filter spectra that can be generated robustly from received light over short optical path lengths. The complex filter spectra provide data that can be converted to a spectrum of the received light using compressed sensing techniques. The result is a more compact, easily manufactured spectrometer.
