Paper Abstract

Fourier Transform Spectrometers usually consist of a single telescope with the beam split into two paths prior to the focal plane. The beams form a Michelson interferometer with beam recombination occurring at the focal plane. The path length of one beam is varied in order to scan through the white light fringe packet while a series of images is collected. Fourier transforming each pixel of the image across the series results in a spectral data cube of the scene. We propose using a multiple telescope FIzeau Imager for collecting Fourier Transform Spectrometer data. The path lengths through one telescope are varied while a series of images is collected. The processing is similar to the standard IFTS with some modification due to the necessity of image restoration. We present preliminary results from a laboratory multiple telescope FIzeau Imaging system.
