A quantum trick based on interferometric measurements allows a team of researchers at LMU to detect even the smallest ...

“The non-invasive in vivo optical imaging of rhodopsin activation extends the diagnostic capability of ORG and may facilitate ...

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.

The Event Horizon Telescope has accomplished what no other telescope or telescope array has ever done: imaged the event horizon of a black hole directly. A team of more than 200 scientists using data ...

When Hanbury Brown and Twiss (HBT) first proposed that intensity fluctuations of light measured at two different locations carry information on the size of the light source, they met with strong ...

This image compares data from two Iceye Synthetic Aperture Radar images. Changes in the vertical height of the surface appear black. Areas without changes are depicted in white. Credit: Iceye SAN ...

Almost a century ago the concept of measuring surface roughness started as a way to stop disputes and uncertainty between buyers and manufacturers. Today, it is a common identifier that is utilized ...

Dynamic interferometry allows precise optical measurements to be made on the factory floor. Steve Martinek explains the principle and technology behind the technique. The high-precision interferometry ...

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 ...
