This manual provides a brief introduction to the
CFHT Fourier Transform Spectrometer (FTS); it discusses the general design of the instrument in a
nontechnical fashion as well as the basic procedures for its operation.
Those interested in a more detailed technical discussion
should consult ``Active Control For a Fourier Transform Spectrometer''
by J.-P. Maillard and G. Michel (Proceedings of IEEE Regional 6
1981) and ``An Astronomical Fourier Transform Spectrometer'' by P. Connes
G. Michel (Applied Optics, Volume 14, pp. 2067, 1975). The latter
article describes an instrument which is in many ways similar to the
CFHT FTS. The CFHT FTS itself is discussed by Maillard and Michel in ``A
High Resolution Fourier Transform Spectrometer For The Cassegrain Focus
At The CFH Telescope'' (Instrumentation for Astronomy with Large Optical
Telescopes, ed. C.M. Humphries, p. 213-222. An excellent review of
interferometers in general can be
found in ``High Resolving Power Fourier Spectroscopy'' by H. Sakai, which
Chapter 1 of the book ``Spectrometric Techniques Volume'' (Academic
1981) and the text ``Fourier Transform Infrared Spectrometry'' by P.R.
Griffiths and J.A. de Haseth provides a wealth of information. Finally,
S. Johnston's ``Fourier Transform Infrared'' (Ellis Horwood, 1991)
provides a very interesting historical summary of Fourier transform
This manual does NOT include a discussion of data reduction techniques
and software for use with CFHT FTS data. Instead, the user should refer
to the manual
The CFHT Fourier Transform Spectrometer Data Reduction Program Users' Guide , by Bohlender and Link for
information on reducing CFHT FTS scans. This document is available in
hardcopy form or can be accessed from Xmosaic.
It should be pointed out that this manual is a somewhat expanded version
of an earlier draft written by Dr. Timothy Davidge during his tenure as
a CFHT Resident Astronomer. However, the current author assumes full
responsibility for any errors or omissions occurring in this final
version of the manuscript. Any questions or comments should be referred
