Interferometric system for detecting radiation wavelength shift functions based on a Fabry-Perot interferometer. Means
developed for enhancing the system performance are described, namely: a method of increasing illumination of detected
fringes for enhancing the system sensitivity, and a method of compensating interference maxima spreading caused by
misalignment of mirrors that allows enhancing accuracy of light frequency shift measurement. The way to increase
detected fringe brightness is based on additional reduction of the divergence of passing through the interferometer light
beam. This method allows compensating negative effect of collimating lens spherical aberrations, and, using them,
increasing the detector illumination. The way of compensating the interferometer mirrors misalignment effect on the
detected fringe is based on use of specific relative position of beams from various parts of the interferometer near the
focal plane of the focusing lens.
