Measuring methane emissions and leaks is important to a variety of industries because the gas contributes to global warming and air pollution. "Agricultural and waste industries emit significant amounts of methane," ...

 E-Mail IMAGE: The miniaturized optical filter is located in the central slot of the sleeve mount. view more  Credit: © Uni Bonn Scientists at the University of Bonn have built hair-thin optical fibre filters in a very simple way. They are not only extremely compact and stable, but also colour-tunable. This means they can be used in quantum technology and as sensors for temperature or for detecting atmospheric gases. The results have been published in the journal Optics Express. Optical fibers not much thicker than a human hair today not only constitute the backbone of our world-w...

3D imaging with LEDs and smartphone points to simpler machine vision 20 Jan 2021 University of Strathclyde project creates images without complex synchronizing of camera and lighting. Monkey seen: imaging with overhead LEDs An approach to 3D imaging employing conventional LED room lighting and a smartphone could led to more straightforward visualization methods for industrial or security applications. The new method has been developed by a team at the University of Strathclyde Institute of Photonics and Bristol Robotics Laboratory, in work supported by the UK EPSRC QuantIC research program....
