Purdue faculty dedicate countless hours to exploring the frontiers of their respective fields, pushing the boundaries of knowledge and contributing to the ever-evolving landscape of academia. To ...

High harmonic emission occurs when an electron, liberated from a molecule by an incident intense laser field, gains energy from the field and recombines with the parent molecular ion. The emission ...

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 ...

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 ...

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 ...

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.

Modern semiconductor manufacturing technology has advanced rapidly. Because of this, measurement using non-contact displacement and transparent coating thickness has become very critical. Applications ...

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 ...
