A Michelson interferometer with the facility for step and integrate, and rapid scan operation has been used for Fourier transform PAS. The merits of the two methods were considered. The versatility of this technique for the measurement of the infrared spectra of powdered samples has been demonstrated. Some possible reasons for the distortion of such measurements have been discussed. " FT-PAS has enabled discrimination between K N03 and K NOj and has shown the technique to be suitable for quantitative analysis of solid mixtures. ... [Pg.23]

An idealized Michelson interferometer is illustrated in Figure 3. The interferometer modulates the incident beam by changing the optical path difference of the interferometer. The optical path difference can be changed continuously or in increments, methods called rapid scanning and step scanning, respectively. [Pg.3722]
