An All-Reflection Fourier Transform Interferometer for the 500- to 1000- Micrometer Wavelength Region.

Abstract

An all-reflection, two-beam interferometer has been designed, constructed, and tested. It may fill the need for a rugged, cryogenically coolable instrument for space applications. The interferometer uses a grating with symmetric grooves as a beam splitter. Each of the two arms contains a blazed grating with identical groove spacing to nullify the dispersion caused by the beam splitter. A model operated essentially as anticipated. An effect due to the asymmetric displacement of the side gratings with respect to the beam splitter has been explained both theoretically and experimentally. (Author)
