A Fourier Transform Spectrometer (“FTS”) system includes a Fizeau FTS having a plurality of sub-collecting elements, adjacent ones of which are separated by a gap distance, and at least one of which has an adjustable optical path. The FTS system further includes a Michelson FTS having an adjustable optical path. The FTS system further includes one or more processors configured to select spectral data collected by the Fizeau FTS corresponding to spatial frequencies for which the Fizeau FTS has a modulation transfer function (“MTF”) value above a first threshold level, to select spectral data collected by the Michelson FTS corresponding to spatial frequencies for which the Michelson FTS has a MTF value above a second threshold level, and to combine the selected spectral data from the Fizeau FTS with the selected spectral data from the Michelson FTS.
A Fourier transform spectrometer (“FTS”) system comprising:
A method of restoring low spatial frequency spectral information to an image using a Fizeau Fourier transform spectrometer (“FTS”) and a Michelson FTS, the method comprising the steps of:
A machine-readable medium carrying one or more sequences of instructions for restoring low spatial frequency spectral information to an image using a Fizeau Fourier transform spectrometer (“FTS”) and a Michelson FTS, wherein execution of the one or more sequences of instructions by one or more processors causes the one or more processors to perform the steps of:
