Fizeau Interferometer - Definition and Applications

WebApr 7, 2024 · The main applications are in the following fields: (1) surface profiling applications using two-beam Fizeau interferometers, (2) selection of single cavities out of a series of interlaced cavities, and (3) sensitivity enhancement for multi-beam interferometers for planeness or sphericity measurements. WebIn addition to the polarizing interferometric methods, Sykora and de Groot also presented a type of dynamic Fizeau interferometer using the single-frame carrier fringe method [8]. However, the ... WebA fizeau interferometer is a type of interferometer noted for producing narrow multiple-beam interference fringes. As a result, when compared with the Twyman-Green, the Fizeau interferometer has fewer optical components, does not have the large beamsplitter and can be adjusted to a greater accuracy.

Laser Fizeau Interferometer History - Apre Instruments

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. WebAn often used type of wavemeter is based on a Michelson interferometer.
