ABSTRACT:
The correction method of the invention synthesizes a distortion-free interferogram (or spectrum) from a measured interferogram, which has been distorted by detector non-linearities, and a finite series of orthogonal functions derived therefrom. The coefficients of the series of functions are selected with a priori knowledge about the limited spectral sensitivity of the radiation detector, preferably with the method of Gaussian least squares fit of observation, such that the resulting spectrum assumes the value of zero of the distortion-free spectrum outside of the sensitivity range, and in freely-definable ranges. The method of the invention can be used to correct detector non-linearities, as occur in Fourier spectroscopy.
