Paul Urbach graduated in 1981 at the University of Groningen, the Netherlands, and completed in 1986 a Ph.D. thesis at the same university on the optimization of hydrodynamic propulsion. In 1986, he joined Philips Research Laboratory in Eindhoven, the Netherlands. During 1980, he spend four months in Signetics Research Laboratory in Sunnyvale, California, the USA, where he worked on optical lithography. In 1994, he became a principal scientist at Philips Research Laboratory. In 2000, he became a part-time professor in diffraction optics at Delft University of Technology (TUDelft), the Netherlands. Since January 2008, he is a full professor and the head of the Optics Research Group of TUDelft. He has been President of the European Optical Society 2012-2014 and 2017-2018, member of the Advisory Board of the Dutch Minister of Economic Affairs on metrology and Scientific Director of the Dutch Optics Centre.Deren Li, born in December 1939, is an Academician of the Chinese Academy of Sciences, the Chinese Academy of Engineering, the International Eurasian Academy of Sciences (IEAS), Corresponding Academician of the International Academy of Astronautics (IAA) and Honorary Member of the International Society for Photogrammetry and Remote Sensing (ISPRS). Li, also a professor of Wuhan University and a PhD supervisor, is the director of the Academic Committee of Wuhan University, the director of the Academic Committee of the State Key Laboratory of Information Engineering in Surveying, Mapping and Remote Sensing, and the director of the Collaborative Innovation Center of Geospatial Technology. He has been the director-general of the Chinese Society for Geodesy Photogrammetry and Cartography, vice director of the China Society of Image and Graphics, vice director of the Association of Environment Remote Sensing of China (AERSC), founding president of the Asia GIS Association, and president of Committee III and VI of the International Society for Photogrammetry and Remote Sensing. He is also a member of the National Aerospace Expert Group, deputy leader of the National Key Program for Science and Technology Development--"High-resolution Earth Observation System", member of the Sixth Science & Technology Commission of the Ministry of Education and member of the Strategic Research Committee. He has won one National Science and Technology Progress Award (Innovation team), four Second Prizes of the National Science and Technology Progress Awards and two National Higher Education Teaching Achievement Prizes (1st place). Dengyun Yu, deputy director of the China Aerospace Science and Technology Corporation CST. He has long been engaged in systematic designing of spacecraft, theoretical research of dynamic, development of analysis software, and related organization and management work. He has participated in, or organized the analysis and research about the impact dynamic of spacecraft, the vibration mechanics of remote sensing satellite, the dynamic of manned spacecraft docking in space, the complex dynamic of space station and so on, where he achieved substantial achievements.
