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 ...

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 ...

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 ...

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 ...

Astronomers have long struggled to capture the true nature of stellar nova explosions. However, thanks to cutting-edge ...

Accurately controlling film thickness and uniformity is extremely important for both throughput and performance in the automotive, aerospace, semiconductor, medical, and research industries. White ...

This application note describes the measurement and analysis advantages that white light interferometry (WLI) offers for the various CMP components. It also details an improvement study that ...

Nova explosions, which were thought until now to be relatively simple, are actually turning out to be very different. An ...

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 ...

University of Illinois Physics Professor Paul Kwiat and members of his research group have developed a new tool for precision measurement at the nanometer scale in scenarios where background noise and ...

Astronomers have obtained remarkably detailed images of two stellar explosions -- called novae -- just days after they began.
