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

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 ...

White light interferometry (WLI) is a contact-free optical method for measuring surface height. It uses the phase difference between the light reflected off a reference mirror and the target sample to ...

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 ...
