researchers from the National Institute of Standards and Technology (NIST) have been developing a laser power sensor that could be built into manufacturing devices for real-time measurements in many manufacturing processes, from welding car parts to crafting engine components with 3D printers.
When light pulses from an extremely powerful laser system are fired onto material samples, the electric field of the light rips the electrons off the atomic nuclei. A plasma is created. The electrons couple with the laser light in the process. When flying out of the target, they pull the atomic cores behind them. In order to experimentally investigate this complex acceleration process, researchers from the German Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have developed a novel type of diagnostics for innovative laser-based particle accelerators.
A new discovery of a light-induced super photobase at Michigan State University is revealing some of photosynthesis' desirable traits. The interdisciplinary team of scientists was able to document the ultrafast dynamics of the super photobase that is 10 million times stronger than anything previously discovered.
By creating a new twist on fiber optic sensors, researchers in China have developed a smart, flexible photoacoustic imaging technique that may have potential applications in wearable devices, instrumentation and medical diagnostics.
Covert sensing of objects around a corner may soon become a reality. Aristide Dogariu, a University of Central Florida Pegasus Professor of Optics and Photonics, and his colleagues published a paper in Nature Communications this month demonstrating how to passively sense an object even when direct vision is impeded.
New four-year study data shows the significant impact of a pioneering contact lens management approach to slowing the progression of myopia (nearsightedness) in children, including those whose treatment begins later. CooperVision is presenting the latest outcomes during the BCLA Asia conference in Singapore this week, at which the globally increasing prevalence of myopia is among the most widely discussed issues.
An experiment at the University of Nebraska-Lincoln demonstrated how the application of intense light boosts electrons to their highest attainable speeds.
Scientists have developed a topological photonic chip to process quantum information, promising a more robust option for scalable quantum computers. The research team, led by RMIT University's Dr Alberto Peruzzo, has for the first time demonstrated that quantum information can be encoded, processed and transferred at a distance with topological circuits on the chip. The research is published in Science Advances.
The properties of quantum mechanics can be utilized, for example, in technology and encrypting messages, but the disadvantage is the occasional disappearing of information. For the first time, a research group consisting of Finnish and Chinese scientists has found a way to fully control the information escaping the qubit.
Researchers have developed a combination of commercially available hardware and open-source software, named PySight, which improves rapid 2D and 3D imaging of the brain and other tissues.
