The number of mirrors typically used in Michelson Interferometer is 2. I am looking up the respective Wikipedia article and MIT's youtube video. I am wondering, for the sake of one of my experiment, whether more than 2 mirrors can be used in the interferometer? I require the traversing mirror to be in a remote location and moving is a non-orthogonal line. I intend to use more mirrors to get the interference pattern. I wish to know if this is feasible.
