Interferometers

Interferometers are a tool used in science and other related industries to measurement small displacements, refractive index changes, and surface irregularities. This is done by a technique in which waves usually electromagnetic, are superimposed in order to extract information. In the process of interferometry, light is analysed in terms of absorption or emission to return results on surface profiles. Interferometers are tools used in fields of Interferometry is an important investigative technique in the fields of astronomy, nuclear and particle physics, fiber optics, quantum mechanics, engineering metrology, , optical metrology, oceanography, seismology, spectroscopy, plasma physics, remote sensing, biomolecular interactions, velocimetry, surface profiling, microfluidics, mechanical stress/strain measurement and optometry.
