A Multiple-Beam Michelson Interferometer for the Far Infrared

Kunio Yoshihara, Katsuhiko Okada, Atsuo Kitade

Abstract

Multiple-beam interference occurs in the Michelson interferometer when a semi-transparent mirror is inserted between the radiation source and the beam-splitter. This phenomenon is analyzed in detail and method of reconstructing the spectrum from the interferogram obtained with such an interferometer is described. Reconstructed spectra using an electronic computer are in good agreement with the assumed original spectra.
