Faraday rotator mirror

Michelson proposed an interferometric apparatus in 1890 following an earlier suggestion by Fizeau. The invention became the precursor of many important modern optic measurement techniques. The Michelson Interferometer, as it is called, is used to measure small optical path length changes. The classic Michelson Interferometer consists of two mirrors (one forming …
