Passive tilt compensation in an FTS using a double-sided flat retroflector
Abstract
An optical configuration for a tilt-compensated Fourier transform spectrometer is presented. An expanded and collimated He-Ne laser beam was passed through the interferometer and the collimated output was observed visually. The double-sided mirror was tilted through angles approaching 1 deg with no apparent degradation in the interference quality.
