Sažetak
We have investigated the intrinsic accuracy of the optical frequency scale in spectra acquired by a Fourier Transform Spectrometer (FTS). The uncalibrated accuracy of the FTS optical frequency axis is about 1 part in 105. This uncertainty can be reduced by at least two orders of magnitude using a multiplicative calibration correction derived from a single wavelength standard line. The work reported here describes a new approach to accurate calibration of the wavenumber scale for a UV visible FTS, which we have used to measure accurate wavenumbers and Ar pressure shifts for the prominent lines of 198Hg.
