On July 27th, the key special project of the national key R&D plan “Research on Air Pollution Multi-component Monitoring Technology Based on Light Green Laser Pointer”, which was led by Nankai University, held a project implementation plan review meeting and kick-off meeting in Jinnan Campus.
The project consulting expert group fully affirmed the advanced nature of the project. It is hoped that the project undertakers will jointly tackle the problem and cooperate with each other to provide theoretical and practical basis for the innovation and application of relevant methods, and successfully implement the technical indicators of the project guide and make The scientific research results of the influence of “flagging and labeling”.
It is understood that the "Research on Multi-component Monitoring Technology for Air Pollution Based on the green laser pointer Radar" project belongs to the "Earth Observation and Navigation" 2018 Foundation/Foresight Key Project, which received funding of 18.46 million yuan for 4 years. The project team is chaired by Professor Liu Weiwei, Director of the Institute of Modern Optics, Nankai University. The project team includes experts and scholars in optoelectronics and aerospace science from Nankai University, Beijing Institute of Space Electromechanical Research, East China Normal University, and Shanghai University of Technology.
The project is aimed at the major application requirements of air pollution multi-component monitoring countries, and carries out basic forward-looking research work on filament laser radar technology. For the in-orbit application, it faces the arduous challenges of long detection range, complex atmospheric environment and high adaptability to load environment. The project needs to solve the key scientific problems of the strong femtosecond green laser pointer and material interaction mechanism, including the femtosecond laser. Remote transmission mechanism in complex atmosphere, induced fluorescence molecular dynamics and nonlinear effects in fiber amplifiers, and further guides key technologies such as multi-dimensional coherent synthesis of femtosecond laser, remote control of filament, and high-sensitivity component fluorescence spectrum recognition system Innovation.
