Adhikari has been involved in the construction and design of gravitational-wave detectors since 1997. [19] He started working on laser interferometers as a graduate student at MIT, with a particular focus on the variety of noise sources, feedback loops and subsystems, [20] [21] and helped to reduce the noise in all 3 of the LIGO interferometers while working on the Livingston interferometer.
A laser is divided into two beams by a beam splitter tilted by 45 degrees. The two beams propagate in the two perpendicular arms of the interferometer, are reflected by mirrors located at the end of the arms, and recombine on the beam splitter, generating interferences which are detected by a photodiode. An incoming gravitational wave changes ...
The MIT study established the feasibility of interferometers at a 1-kilometer scale with adequate sensitivity. [22] [26] Under pressure from the NSF, MIT and Caltech were asked to join forces to lead a LIGO project based on the MIT study and on experimental work at Caltech, MIT, Glasgow, and Garching. Drever, Thorne, and Weiss formed a LIGO ...

Electronic speckle pattern interferometry (ESPI), [1] also known as TV holography, is a technique that uses laser light, together with video detection, recording and processing, to visualise static and dynamic displacements of components with optically rough surfaces. The visualisation is in the form of fringes on the image, where each fringe ...
Profile of a shockwave going through a solid, Adapted from Marc Meyers's "Dynamic Behavior of Materials". Velocity interferometer system for any reflector (VISAR) is a time-resolved velocity measurement system that uses laser interferometry to measure the surface velocity of solids moving at high speeds.
