Michelson Interferometer

  1. Sep 20, 2012 #1
    I would like an outside opinion on something I've been thinking about lately. If one of the outer mirrors on a Michelson interferometer was to be misaligned by a small angle of theta, what would be the shape of the interference pattern in the detector plane? What would happen to this pattern as the other mirror moves?

    Do you have access to some simple items to make an interferometer? A laser source, a beamsplitter (microscope slide would do), two first surface mirrors and a white paper screen: and you're there! Build it yourself and try misaligning one mirror. I once saw this setup functioning in a sandbox. The beamsplitter and mirrors were on posts stuck into the sand. Experiment!
