Michelson Interferometer is an optical precision instrument used to research spectroscopy and metry cooperative designed by A.A.Michelson and E.W.Morley in 1883. It can be used to measure tiny length and change accurately and the related interferometer by its principle are widely used in many fields such as production and scientific research.
In this experiment, the students can undertstand the principle of Michelson Interferometer and the conception of equal inclination interference, learn how to measure wavelength and the thickness of filmy dielectric with a Michelson Interferometer.
Main points:
a) Structure, principle and adjustment of Michelson Interferometer
b) Phenomenson of equal inclination interference observation, length of inclination interference measurement
