Optical interferometry basics
WebOptical interferometry is a method of measuring distance changes with a precision down to sub nanometer scale. By use of imaging techniques the acquisition of surface profiles is also possible. The profile is derived from the relative or absolute phase of the reflected light for each profile point. WebAn interferometer is an instrument that compares the position or surface structure of two objects. The basic two-beam division of amplitude interferometer components consists of a light source, a beamsplitter, a …

WebModern long-baseline optical interferometry started approximately 30 years after radio interferometry, following the pioneering experiments and important scientific results with the Narrabri intensity interferometry (e.g., Hanbury Brown et al. 1974) and the heterodyne work of the Townes’ group at Berkeley (Johnson et al. 1974).The first successful direct … WebOptical coherence tomography (OCT) is a 3-D imaging technique that can provide high resolution imaging in a scattering media, non-destructively and without the need for contact or a coupling medium. Lateral imaging …
WebOct 9, 2006 · Optical interferometry is used in communications, medical imaging, astonomy, and structural measurement. With the use of an interferometer engineers and scientists are able to complete surface inspections of micromachined surfaces and semiconductors. Medical technicians are able to give more consise diagnoses with the employ of … WebA basic interferometer creates two beams from one source and sets up an interference pattern by combining a fixed reference path with a moving test path at the detector. Coherence between two waves refers to the ability of the waves to interfere with each other in an observable way.
