1. Resource Description

   "Researchers in the University of Hawaii's Free-Electron Laser Group have developed a Fourier transform spectrometer based on a modified Sagnac interferometer. The instrument uses two gratings as dispersive elements to greatly improve the spectral resolution, and in-line optics to match the beam size in the interferometer to optimize the efficiency. A CCD or photodiode array is used as the detector and the fast Fourier transform of the fringe pattern is performed by a computer."
