Michelson Spectrometer System

A new and optically very simple Michelson Fourier Transform Spectrometer has been developed. The development includes full consideration of the data processing problems and their solutions. The raw data are recorded on analog tape at the telescope, but digitization and all succeeding reductions are performed by digital computers. All the necessary data reduction software is complete, and we demonstrate that they produce spectra whose resolution compares favorably to the 5- and 16-A/mm Coude spectra in the Hiltner and Williams Stellar Spectral Atlas. The first results from this spectrometer have been published as "An Atlas of Stellar Spectra," Volumes I and II, whose wavelength coverage is between 0.4 and 1.0 pm. The atlas is available in digital tape format from the National Space Science Data Center, NASA-Goddard Space Flight Center, Greenbelt, Maryland 20771.© (1979) COPYRIGHT SPIE--The International Society for Optical Engineering.
