Abstract
Fourier Transform Spectroscopy is performed using a birefringent device to vary path difference systematically for all regions of an image simultaneously, so that a separate interferogram is collected for each image region by combining intensity values in multiple images. The optics may allow a theoretical efficiency of 100% in light throughout.
