While the entangled orbital angular momentum (OAM) photons propagate through the turbulent atmosphere, the OAM entanglement is decoherent. Adaptive optics (AO) system is an effective technique to mitigate wavefront distortion induced by atmospheric turbulence. In this paper, we investigate the performance of the system when the entangled OAM photons propagate though atmospheric turbulence with AO...
It's the trend that sensor network become more standardized and unified as internet of things develops continuously. Aiming at resolving the problems arising from variety of sensors type and interface, this paper presents a design idea of a standardized sensor network node based on virtual instrument and IEEE 1451 standard, and expounds the realization of this sensor node. A concept of sensor node...
Vibration detecting system provides a monitor method for the equipment in normal work condition. A good detection system should get working statues of all components and transfer them to the terminal in time, so the system must have good real time performance. In this paper, we have realized a real-time Linux system for the self-designed vibration detecting system, coupled together with RTLinux patches...
Steady high magnetic field facility (SHMFF) is a basic tool for many scientific experiments and its control-monitoring system is the core part which supports experimental devices and subsystems for safe and reliable operation. The control-monitoring system of SHMFF with hierarchical structure is based on network-distributed measurement and control technology, including User Control System, Operator...
