The interference microscope is an integration of microscope and interferometers, the shapes of which can be classified as (1) Michelson, (2) Mach-Zehnder, (3) cyclic and (4) common-path or polarization interferometer. After introducing general principles of two-beam interferometry, the author reviews the techniques of interference microscopy and the principles of various types of interference microscopes according to the above-mentioned classification. Some remarks are given on its future possibilities including the use of lasers.
