Chinese research team from Shanghai Advanced Research Institute and the Shanghai Institute of Optics and Fine Mechanics of the Chinese Academy of Sciences has developed an advanced imaging technique to achieve super-resolution microscopy at unprecedented speeds and with many fewer images. The new method should make it possible to capture processes in living cells at speeds not previously possible.
Recently, Prof. GAO Hongjun Gao's and Prof. DING Hong's joint research group from Institute of Physics and University of Chinese Academy of Sciences (IOP/UCAS) took a step further in the research of Majorana physics using the home-upgraded ultra-low-temperature and strong-magnetic-field scanning tunneling microscope/spectroscopy (STM/STS) system.
Recently, a research team led by Prof. FENG Yan from Shanghai Institute of Optics and Fine Mechanics of the Chinese Academy of Sciences, reported a high power CW single frequency 780 nm laser by utilizing single-pass frequency doubling of a 1560 nm fiber amplifier in an MgO: PPLN crystal.
Dr. LI Qiaoling, Prof. YAN Xiaoli and the collaborators from Fuxian lake solar observatory of Yunnan Observatories of the Chinese Academy of Sciences recently analyzed the formation and decay process of sunspot penumbra in the active region NOAA 12673. Their study is very important for understanding the evolution of sunspots and solar dynamo. In the future, the researchers plan to analyze more examples to address this issue by using high-resolution observations from the New Vacuum Solar Telescope (NVST) and other instruments.
Recently, researchers at Shanghai Institute of Optics and Fine Mechanics have introduced the concept of tri-focal Fibonacci sieve into telescope and successfully realized tri-planar identical copies, which met the single-shot requirement of curvature sensing.
The weak optical signal detection are overwhelmed by strong scattering noise when propagating through a scattering medium. The extraction and reconstruction of weak optical images completely overwhelmed by strong noise is a fundamental scientific problem and a key technology bottleneck in weak optical signal detection. For the first time, XIOPM research team theoretically and experimentally demonstrated, the weak white-light image reconstruction via optical stochastic resonance based on spatially incoherent modulation instability.
