Tilt-compensated Michelson interferometer for Fourier transform spectroscopy.
A new Michelson interferometer built exclusively with spherical and plane mirrors provides tilt compensation for all mirrors. In particular, a staggering of the movable mirror generates no shift of the two images obtained from the two interferometer arms on the detector area. These properties are experimentally demonstrated by taking interferograms from a near ir source. The influence of small tilts of the movable component on the optical path difference is analyzed.
