Mach Zehnder Interferometers

A Mach Zehnder interferometer is an interferometer derived from the Twyman-Green interferometer. Light passing through a sample region in one direction recombines with a second leg without traversing the sample twice. The instrument is used to study transparent objects and is particularly useful in studying wind tunnel gas dynamics.

Glossary

Mach-Zehnder interferometer A Mach-Zehnder interferometer is an optical device used to measure the phase difference between two collimated beams of light. It is named after the physicists Ludwig Mach and Ludwig Zehnder, who independently proposed the design in the early 20th...
interferometer An interferometer is a scientific instrument that utilizes the principle of interference to measure differences in the path length, wavelength, phase, or amplitude of coherent electromagnetic waves. It typically consists of components such as a...
surface profile A representation of the shape of a surface, including any roughness or other irregularities. The profile can be generated by direct measurements, as by a stylus, or by remote measurement, as by an interferometer.
