In a recent study, researchers from China have developed a chip-scale LiDAR system that mimics the human eye's foveation by dynamically concentrating high-resolution sensing on regions of interest ...

Scientists developed a two-photon-enhanced metasurface that cuts photon requirements for nanoscale displacement measurement ...

Abstract: To adapt the demands of the high-speed and real-time dynamic measurements, a linear array sensor (LAS) and projection fringe-based vision system was proposed to measure the radial vibration ...

Abstract: A cascaded Fabry-Perot interferometer (FPI) for displacement sensing with the Vernier effect is proposed and experimentally demonstrated. The sensor consists of a single mode fiber (SMF) ...
