WebCompared with Michelson-type interferometers for ultrahigh resolution spectral measurements, the spectrometer is much smaller in physical size and shorter in measurement time. Compared with the combination of a FPI and a Michelson-type interferometer, the spectrometer has much shorter measurement time and higher stability. http://hyperphysics.phy-astr.gsu.edu/hbase/phyopt/michel.html

WebFor the ordinary Michelson interferometer the term in sin 2 i dominates, which is the same as for the Fabry–Perot spectrometer when the term (1 − cos θ is approximated. This is why these devices have quadratic angular dispersion. With dispersion of fourth order, the optical path difference changes very slowly with angle. map of houndsditch
