Paper Abstract

A dual beam FTIR is described in which both beams generated from a Michelson interferometer are detected. The Michelson interferometer used for this study contained cube-corner retroreflectors instead of flat mirrors. The retroreflectors could be used to access the modulated beam normally superimposed on incoming source radiation. Matched MCT detectors were used to measure each modulated beam. The output from these detectors were summed before digitization to reduce the dynamic range of the signal and minimize digitization noise.
