Digital Signal Processing of Fourier Transform Spectra on IBM PC-Compatible Computers

Abstract

The advent of the Los Alamos National Laboratory Fourier Transform Spectroscopy Facility represents a break with past techniques for reducing Fourier transform data. In contrast to system dependent mainframe reduction packages, the LANL data reduction is performed exclusively on Apple MacIntosh II microcomputers. For scientists involved in Fourier transform spectroscopy there is a need for a unified data reduction package that will accomodate high resolution spectra from both the LANL FTS Facility and the McMath Fourier Transform Spectrometer at Kitt Peak. An adaptation of the Kitt Peak code DECOMP is presented that facilitates the reduction of spectral data from either laboratory on IBM PC-compatible computers.
