WebOne type of interferometer that is often used for characterizing a surface of a test object is a Fizeau interferometer. In many embodiments, phase shifting for object surface profiling proceeds by mechanical translation of the reference surface or by wavelength tuning, during which time a computer captures successive frames of an interference ... A highly simplified representation of Fizeau's 1851 experiment is presented in Fig. 2. Incoming light is split into two beams by a beam splitter (BS) and passed through two columns of water flowing in opposite directions. The two beams are then recombined to form an interference pattern that can be interpreted by an observer.
