interferometer 1. Instrument designed to measure the wavelength of light, the refractive index of a medium, as well as the flatness, thickness, the quality of optical surfaces, etc. The interferometer is based on the phenomenon of interference between two coherent beams of light. 2. Name given to several types of clinical maxwellian view system used to measure visual acuity. See clinical maxwellian view system. How to thank TFD for its existence?

| The Xi-100 is said to complement the company's XP Series of stylus-type surface profilers by combining white light and phase-shifting interferometry for precise, non-destructive surface measurements that are internally and permanently referenced to a standard wavelength of light, according to the literature. The more technical description is: "Non-contact, three-dimensional surface measurement using frequency modulated and optical phase-shifting interferometry. They highlight new results and developments in such topics as neutron electric dipole moment searches, neutron optics and interferometry, Standard Model tests using neutron beta decay, neutron facilities, neutron polarimetry, and nucleon-nucleon interactions. |
