(Nanowerk News) A team of researchers has developed a way to significantly increase the memory of speckle patterns, the very complex patterns that result from shining a laser light onto an opaque ...

The challenge of recovering image data from objects hidden from direct observation or concealed by corners, termed non-line-of-sight imaging (NLoS), can be tackled in several ways, often involving ...

WASHINGTON--(BUSINESS WIRE)--Using pseudo-random speckle patterns is an efficient way to image targets, but most approaches require bulky, expensive, complex and slow machinery. To apply this ...

Motivated by the limitations of scanning approaches to photoacoustic microscopy, an international group supervised by Emmanuel Bossy of Université Grenoble Alpes experimented with structured ...

This video is taken from the same sample of blood featured in the Speckle Pattern in Unclotted Whole Blood video after 10 minutes. In this case, the time-varying fluctuations of the speckle pattern ...

The use of lasers in fire detection systems usually involves detecting the variation in a laser beam's amplitude caused by the fire or its effects, but factors such as dust or steam can cause enough ...

Engineers have developed a method for extracting a color image from a single exposure of light scattered through a mostly opaque material. The technique has applications in a wide range of fields from ...

It sure sounds like “laser speckle imaging” is the sort of thing you’d need grant money to experiment with, but as [anfractuosity] recently demonstrated, you can get some very impressive results with ...

Researchers have developed a new laser-based system that offers an efficient and low-cost way to detect fires in challenging environments such as industrial facilities or large construction sites.
