Warming up: illustration of the interferometer. (Courtesy: APS / Alan Stonebreaker) An atom interferometer that does not have to be cooled to cryognenic temperatures has been created by physicists in ...

White light interferometry (WLI) is a contact-free optical method for measuring surface height. It uses the phase difference between the light reflected off a reference mirror and the target sample to ...

Researchers have moved a step closer to achieving quantum-noise-limited measurements using laser interferometry – a technique routinely employed for detecting the motion and displacement of tiny ...

Fringe conference can be traced to the automatic processing of fringe patterns. The term “patterns” evokes an image of flowing lines elegantly wrapped around surface contours. However, automatic ...

Microlenses have many applications, such as coupling light into fiber optics, enhancing light source uniformity in microdisplays, and focusing light onto imaging sensors in mobile phone cameras.

Grating-coupled interferometry (GCI) is a surface based, a label-free optical sensing technique used for real-time binding kinetic measurements. 1 Typically, GCI is used to detect binding events ...
