The Lummer-Gehrcke type is interesting for its use of only one main component, and is useful in the study of hyperfine structure. The Fizeau-Laurent version is used to detect imperfections in flat surfaces, while lenses and prisms are tested using the Twyman-Green type, a variation of the most famous example. An etalon is used in the Fabry-Perot version of this device, but the most famous is the one used to disprove the existence of ether by Michelson and Morley. FTP, what is this instrument named for its production of optical interference fringes?
