SO2 detection by dual beam fourier transform spectroscopy
Bar-Lev (1967) described an instrument incorporating a dual detector, dual beam Michelson interferometer, and presented experimental results on the detection of gases in air. A 20 pass, 10 m cell wasExpand

Derivative Traces in Infrared Fourier Transform Spectroscopy
The principles of derivative spectrophotometry have been known for many years, and a variety of instrumentation for producing the first and higher differentials of absorption spectra has beenExpand

Background Elimination in Spectra Generated by Fourier Transform Spectrometers
Two methods are described for reducing or eliminating the background of single-beam spectra obtained by Fourier transform spectrometers incorporating analog data-reduction systems. One method simplyExpand

  • 1 May 1970
The use of Fourier transform spectrometers to measure IR spectra is becoming more widespread, and it seems likely that the high sensitivity, speed, and versatility of these instruments can be used toExpand
The effects of beam spreading on Fourier transform spectra
Abstract It is well known that non-collimated radiation degrades the resolution of spectra obtained with a Michelson interferometer by causing the appearance of fringes other than the central fringe.Expand

The sampling of interferograms for Fourier transform spectra
Abstract The sampling theorem is usually given by a statement to the effect that the sampling frequency must be equal to or greater than twice the highest frequency present in the signal, but greatExpand
