Researchers from the Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP) of the Chinese Academy of Sciences, in collaboration with the Institute of Semiconductors of CAS, developed a double-layer silicon-based optical phased array (OPA) that significantly expands the scanning range of chip-scale LiDAR systems. The study was published in Scientific Reports.
Researchers from the Changchun Institute of Optics, Fine Mechanics and Physics of the Chinese Academy of Sciences, in collaboration with the National University of Singapore, have engineered a dynamic "laser needle" to solve a century-old problem in optical imaging.
Researchers from the Changchun Institute of Optics, Fine Mechanics and Physics of the Chinese Academy of Sciences proposed a novel method using a Shack-Hartmann wavefront sensor (SHWFS) combined with "extended sources" to accurately measure the atmospheric coherence length r. This research provides technical support for evaluating atmospheric turbulence in real-time, especially when observing targets that lack point-like light sources or are obscured by high background noise. The results were published in the journal Photonics.
