On October 22, 2019, the Project Progress Seminar of the Key Project - "All-day Active Hyperspectral LiDAR Imaging Technology" hosted by Professor Gong Wei was successfully held at LIESMARS, Wuhan University. The project is funded by the national key research and development program "Earth Observation and Navigation". As a project responsibility expert, Li Chuanrong, a researcher of the Aerospace Information Research Institute, Chinese Academy of Sciences, was invited to attend the seminar. Xu Hong, the Director of the Office for Earth Observation and Navigation of the Ministry of Science and Technology, Prof. Li Jiancheng, Vice President of Wuhan University, and Prof. Li Deren, Chair of the Academic Committee of Wuhan University, attended the meeting. Researcher Ke Tao, Director of the Office of Scientific Research and Development of Wuhan University, presided over the meeting.
Prof. Li Jiancheng, on behalf of Wuhan University, welcomed the team of experts and officials. On behalf of the project management department, director Xu Hong put forward practical suggestions for project management. Prof. Li Deren and Prof. Chen Ruizhi, Director of LIESMARS, delivered a speech on behalf of the implementation unit of the project. Later, Prof. Gong Wei, the project PI, reported the overall progress of the project. Since the start of the project in May 2018, on the basis of the completion of the optimization design of the whole system, the ground scale system has been developed to verify the designed indicators of the airborne system. Important progress has been made in key technologies such as laser emission, receiving detection, data processing, etc., and a breakthrough has been made in the research of high-energy super-continuum laser source.
Wuhan University is the leading researching and developing institution of the project "All-day Active Hyperspectral LiDAR Imaging Technology". Other involving institutions include Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, Hefei Institute of Physical Science, Chinese Academy of Sciences, and Chinese Academy of Surveying and Mapping. The project was initiated in May 2018 with a four-year implementation period and a total fund of 35.17 million yuan. In order to meet the application requirements of 3D spectral information integrated acquisition and recognition in target detection, the project is developing a new system of LiDAR hyperspectral imaging, which is the leading direction of the development of Earth observation technology. The implementation of the project will promote the demonstrating application of hyperspectral LiDAR in surveying and mapping, forestry and other fields, and lay a technical foundation for the future development of aerospace hyperspectral LiDAR payload.
