Dynamic speckle analysis is a non‐invasive optical technique that exploits the fluctuating interference patterns produced when coherent light, typically from lasers, illuminates a dynamic sample.

Accurate identification of heart disease in living patients is critical for many reasons, but coronary health also affects the suitability of the organ for subsequent use in organ transplantation. In ...

WASHINGTON -- 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 ...

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 ...

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 ...

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.

(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 ...
