Abstract

We describe a novel cryogenically cooled, spatially modulated, imaging, Fourier transform interferometer spectrometer for spectral measurements in the 1 - 5 micrometers range. Using spatial modulation and a detector array to sample the interferogram, the instrument employs no moving parts to obtain spectra. It is extremely robust and potentially more reliable than other interferometers in addition to taking advantage of the multiplexing afforded by array detectors. The instrument technology possesses a unique combination of characteristics which forms a niche for spectral measurement not widely known but of great potential value. These characteristics include broad wavelength range, wide field of view if desired, simultaneous measurement of all spectral channels, compactness, no moving parts, and moderate resolution. We present a small amount of test data derived from the instrument.
