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.
  • TERMS
  • Mach-Zehnder interferometer derived from the Twyman-Green interferometer, the Mach Zehnder is an amplitude splitting interferometer that consists of two beamsplitters and two fully reflecting mirrors. Light from an extended source passes through the first beamsplitter...
  • interferometer An instrument that employs the interference of lightwaves to measure the accuracy of optical surfaces; it can measure a length in terms of the length of a wave of light by using interference phenomena based on the wave characteristics of light....
  • 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.
