Twyman-Green interferometer A testing device that provides a contour map of the emergent wavefront for the observer in terms of the given wavelength of the light.
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....
Twyman-Green interferometry Twyman-Green interferometry is a technique used in optics to measure the flatness or surface profile of optical components with high precision. It is based on the principles of interference of light waves. In a Twyman-Green interferometer, a...
