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

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 ...

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

New high-resolution images show that novae are anything but simple stellar fireworks. One exploded with multiple gas streams ...

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.

It is useful for expanding the effective aperture of the interferometer, in one axis. The measurement area is around the same size as the beam when a laser interferometer's round measurement beam ...

Manufacturing a precision surface requires a balance between satisfying the optimum quality requirements at the minimum cost. Steve Martinek summarizes the challenges of increasing the precision ...

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 ...

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 ...

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 ...
