When observing biological samples under a microscope, if the medium in which the objective lens is located is different from the sample, the light beam will be interfered with. For example, when observing a water sample with a lens surrounded by air, the light bends more strongly in the air around the lens than in water.This interference can cause the measured sample depth to be smaller than the a...
Recently, Fujitsu and KDDI research company have successfully developed a high-capacity multi band wavelength multiplexing transmission technology using installed optical fibers.The new technology of the two companies can transmit wavelengths beyond the C-band by using batch wavelength conversion and multi band amplification technology.Expanding transmission capacity in remote areasTwo companies h...
Adaptive optics is a technique that improves imaging quality by correcting wavefront distortion. Interference focus sensing (IFS), as a new method proposed in the field of adaptive optics in recent years, has been proven to have significant effects in correcting complex aberrations in deep tissue imaging. This technology is based on measuring a single location within the sample to determine the ca...
Recently, the reporter learned from Changguang Satellite Technology Co., Ltd. (hereinafter referred to as "Changguang Satellite") that the company used a self-developed vehicle mounted laser communication ground station to conduct satellite ground laser high-speed image transmission experiments with the onboard laser communication terminal of the "Jilin No.1" constellation MF02A04 satellite and ac...
The Chinese Academy of Sciences reduced the volume of the deep ultraviolet laser by 90% and achieved 193 nm vortex beam output for the first time. Professor Xuan Hongwen described "loading truck equipment into the car trunk". This technology enables a 30% reduction in the size of lithography features, breaking through the bottleneck of the 2-nanometer process. In the next three years, laser power ...
