摘要: Snapshot imaging Fourier transform spectrometers include a lens array that produces sub-images are directed through birefringent interferometer in orthogonal polarization eigenstates acquire an optical path difference. Interference patterns based on this OPD can be transformed to obtain spectral image. In some examples, polarizing gratings provide spatial heterodyne frequency and offset the spectra.
