Abstract

Three modifications of the Michelson interferometer are described to give straight fringes with linearly variable frequency. The modifications are done in such a manner that the order of interference is very low and hence fringes of high contrast are obtained. A brief theory of these modified versions of the Michelson interferometer is presented and conditions are derived for the production of fringes of best contrast.
