On behalf of the project team, Professor Liu Weiwei, the person in charge of the project team, reported the project status, organization and management, management methods and financial management measures. The person in charge of the relevant departments of Nankai University stated that they will fully support and guarantee the implementation of the project. The project cooperation units such as Beijing Space Electromechanical Research Institute also indicated that they will complete relevant research work according to the task division and schedule.

The expert group fully affirmed the advanced nature of the project. It is hoped that the project undertakers will jointly develop and coordinate cooperation, provide theoretical and practical basis for the innovation and application of relevant methods, and successfully implement the technical indicators of the project guide. Flag, labeling, the impact of scientific research results.

The “Research on Multi-component Monitoring Technology for Air Pollution Based on Light-Laser Lidar” is part of the “Earth Observation and Navigation” 2018 Foundation/Foresight Key Project, which received funding of 18.46 million yuan for 4 years. The project team was chaired by Professor Liu Weiwei, Director of the Institute of Modern Optics at Nankai University. The project team included 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 of load environment. The project needs to solve the key scientific problems of the mechanism of interaction between strong femtosecond laser and matter, including the femtosecond laser in complex atmosphere. Medium and long-distance transmission mechanism, induced fluorescence molecular dynamics and nonlinear effects in fiber amplifiers, and further guide the innovation of key technologies such as multi-dimensional coherent synthesis of femtosecond laser, remote control of filament, and high-sensitivity component fluorescence spectrum recognition system .
