Hello the All,

I built a mockup of a static birefringent FT spectrometer of moderate theoretical resolution, based on a Wollaston-type prism and a linear photo diode array.

A preliminary single-sided "raw" interferogram is obtained from a UV lamp (added with band-pass filer 200-270nm).

Also, a 266nm laser interferogram is recorded to evaluate magnification of imaging optics which projects the virtual fringe pattern (localized inside of Wollaston prism) onto the
linear photo diode array.

Would you be so kind to recommend me shortly how to start (surely, if it is realistic in principle) a phase correction of spectrum reconstructed from these data?

Thanks a lot in advance
