Precision measurement based on optics is widely used in advanced manufacturing, including optical critical dimension (Critical Dimension) measurement (submicron accuracy) and TP measurement (Total Pitch) in display panels. The accuracy requirements for dimensional measurement of advanced molds are all on the micron scale. At present, the display panel industry mostly uses imported optical mea...
The processing errors of precision manufacturing have entered the nanometer and sub-nanometer scale from the micron scale in the past. Therefore, the demand for precision measuring instruments in advanced manufacturing industries is becoming more and more extensive, and at the same time, the error requirements are also getting higher and higher. In modern high-end manufacturing, industries in...
Professor Chen Zhichao's optical fiber sensor research team successfully coated silicon optical fibers with new materials for specific chemical and environmental sensing. The research team visited the Department of Chemistry of the Chinese University of Hong Kong to study how to coat the surface of circular silica waveguide structures with this new synthetic material. This collaboration is the...
The traditional implementation methods of underwater wireless communication are mainly divided into underwater sonar communication and underwater radio communication. The communication rates of underwater sonar communication and underwater radio communication are both lower than 10 Mb/s, which cannot meet the future needs of the marine industry for communication networks. As a result, underwa...
