WebFeb 15, 2024 · Interferometry has been a time-honored technique for surface topography measurement. Interferometric measurements of surface shape are relative measurement techniques in which the shape of a known surface is compared with that of an unknown surface, and the difference is displayed as a series of interference fringes. WebFor Fizeau-type interferometers with unequal path lengths, there is a trade-off of the amount of coherence reduction and a reduction of the contrast of the interference fringes. Studying the reasons for the reduction in contrast of a disk-like light source lead to a new invention [6], which is a light source with the shape of a ring concentric ... how to stop being redirected to other sites

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.
