Recently, the "High-precision laser modulation absorption water gas sensor application technology" scientific and technological achievements evaluation meeting was held in the China Science and Technology Hall. China's famous laser and nonlinear optical experts, Chinese Academy of Sciences academician Yao Jianwei, China Huayun Meteorological Technology Group Chairman Wang Xiaoyun, China Aerospace Aerodynamics Research Institute Associate Dean Huang Yuqun, Vice President of China Cultural Heritage Research Institute Ma Qinglin and other 21 experts The judges attended the evaluation meeting. After the discussion of the jury, the technical achievements have a number of core independent intellectual property rights, which are of great significance in the application of humidity measurement, and have broad application prospects and reach the international advanced level.
It is reported that this evaluation will be organized by the China High-Tech Industrialization Research Association, aiming at the scientific, creative and advanced research and development of technical achievements of Beijing Aerospace Yilian Technology Development Co., Ltd., Institute of Semiconductors of Chinese Academy of Sciences and Institute of Electrical Engineering of Chinese Academy of Sciences. Comprehensive evaluation of feasibility, economics and application prospects.
The project team introduced the project from several aspects such as research background, core technology, comparison of domestic and foreign achievements and application of current results. It is reported that the traditional measurement methods in the existing market have low resolution, high humidity hysteresis and large error at low temperature, and after many years of research, Aerospace Yilian has passed a large number of tests and tests to propose laser modulation absorption (TDLAS) water and gas. Sensor application technology allows for higher water vapor measurement accuracy, faster response, and better environmental adaptability. It can be applied to humidity monitoring in many fields such as meteorological environment protection, cultural relics protection, petrochemical industry and electric power.
The experts carefully reviewed the results submitted by Aerospace Yilian. In the project evaluation section, the evaluation committee questioned the relevant content of the project, and the project team answered the expert questions carefully and meticulously. Finally, after the jury discussed, the system was applied for the first time in the domestic high-altitude humidity measurement of UAVs, high-humidity environment monitoring in the cultural relics field, and humidity monitoring of IDC equipment in the data center. The application of the Chinese-language field filled the gap at home and abroad. The technical achievements have a number of core independent intellectual property rights, which are of great significance in the application of humidity measurement, and have broad application prospects and reach the international advanced level.
Academician Yao Jianyu said in an interview that the technology is not China's first, but the research and application in the application field is internationally advanced. In addition, the technology needs to do a lot of work to achieve marketization and industrialization of the application field. At the same time, the expert committee suggested to further expand the application areas of the technology, increase the promotion efforts, and meet market demand.
