Using this basic version a Michelson interferometer setup, one can learn the handling, alignment and measurement techniques of a basic interferometer system. Interferometry is a technique used to investigate optical phenomena through the creation of interference patterns (hence, "interferometer"). Interferometers come in many shapes and sizes all of which, in some way or another, split a light source and then recombine it at the output of the device. Depending on the arrangement of various beam splitters and mirrors, the optical paths of the split beams can be different, and therefore their recombination may result in an interference pattern.
