A Beijing Satellite Navigation Center research group, led by Professor Yijun Tian, has developed a new concept for computing time delay parameters of radio determination service system (RDSS) equipment.
A research group has investigated a novel method for underwater optical communications with OAM demodulation. The results were published in the latest edition of the Journal of Marine Science and Engineering.
Researchers used the topological charge value of the orbital angular momentum (OAM) for classification labels' identification. They analyzed the ocean turbulence caused by different temperatures and salinity.
In a study published in the journal Electronics, researchers explored the effects on the transmission properties of large but finite chains of slots due to different families of disorder: lateral and vertical displacements as well as scatterer manipulation by expanding on previously developed highly efficient method of moment (MoM) implementations.
In a pre-proof article posted in Optics Communications, researchers proposed a novel angle-of-arrival (AoA) tracking device that eliminates the need for beacon lights and beam splitters by employing an integrated beam alignment positioning sensor with a data photo-detector (PD).
On-chip laser frequency combs, which concurrently emit different light frequencies or colors and separate them like the teeth on a comb, are a revolutionary technique for a variety of uses in astronomy, metrology, optical computing, and the environment.
Coherent structures can dramatically affect the flame structure and flame release. Hydrodynamic instabilities are stimulated by thermoacoustic oscillations. Studying how coherent oscillations of various amplitudes can af...
The FLEXPOINT® MVstereo laser module’s primary use is for machine vision applications such as gesture recognition, depth sensing and volume measurement. It delivers an output power up to 100 mW for 660 nm and 130 mW for 830 nm while at the same time being a class 1 laser. It also offers an adjustable focus without removing any of the optics.
The development of cryptographic keys for traditional and quantum cryptography systems, the dependability of today’s modern networked society, stochastic simulation, etc. depend on random numbers.
The leading global forum for light science and technology today launched a new campaign to highlight its values and engage new audiences worldwide.
