Abstract

The optimum parameters of operation for a Fabry-Perot spectrometer used in the equidistant equal-noise sampling method have been calculated. The results, expressed in terms of normalized halfwidths at half-height, are: etalon (a*) = 0.078 (0.095), linewidth (dg*) = 0.13 (0.19), and aperture (f*) = 0.10 (0.19) for temperature (wind) determinations. The etalon widths correspond to rather low reflectivities, namely, 0.62 and 0.56. The critical number of samples, required for unambiguous determinations of a measured profile, are found to be equal to 8 and 12. The usefulness of the equal-noise method in absorption measurements is discussed.
