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 ...

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 ...

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 ...

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

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 ...

Intensity interferometry is a promising technique that enables the precise measurement of spatial properties (i.e., distances, shapes and light properties) by probing fluctuations in the intensity ...

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.
