The Twyman–Green interferometer, invented by Twyman and Green in 1916, is a variant of the Michelson interferometer widely used to test optical components. [58] The basic characteristics distinguishing it from the Michelson configuration are the use of a monochromatic point light source and a collimator.
A simple two-element optical interferometer. Light from two small telescopes (shown as lenses) is combined using beam splitters at detectors 1, 2, 3 and 4.The elements create a 1/4 wave delay in the light, allowing the phase and amplitude of the interference visibility to be measured, thus giving information about the shape of the light source.
The Mach–Zehnder interferometer is a device used to determine the relative phase shift variations between two collimated beams derived by splitting light from a single source. The interferometer has been used, among other things, to measure phase shifts between the two beams caused by a sample or a change in length of one of the paths.
The Twyman–Green interferometer, a double path interferometer, is a variant of the Michelson interferometer that is commonly used to test the precision of optical surfaces and lenses. [ 30 ] [ 31 ] Since reference and sample paths are divergent, this form of interferometer is extremely sensitive to vibration and to atmospheric turbulence in ...
The Twyman–Green interferometer is a variation of the Michelson interferometer used to test small optical components, invented and patented by Twyman and Green in 1916.

Rayleigh interferometer at the National Bureau of Standards In optics , a Rayleigh interferometer is a type of interferometer which employs two beams of light from a single source. The two beams are recombined after traversing two optical paths , and the interference pattern after recombination allows the determination of the difference in path ...
Interferometric microscopy or imaging interferometric microscopy is the concept of microscopy which is related to holography, synthetic-aperture imaging, and off-axis-dark-field illumination techniques.
