I will focus on the optical system design of the 12-meter large optical-infrared telescope, and systematically introduce the optical design methods and the basic principles followed by the design of astronomical optical system, especially large telescopes. I will further discuss the way to evaluate the optical performance and scientific performance of the telescope based on different evaluation criteria. Specifically, the report will systematically compare the optical and scientific performance of classical RC system (three-mirror) and SYZ system (four-mirror). Finally, I will share some of the prospects and plans for the development of future telescopes and astronomical instruments, taking into considerations of the domesitc technical foundation, especially at Tsinghua (THCA), Huazhong University of Science and Technology, and other domestic institutions; with the international collaboration opportunities.

BIO
He was sponsored by the National Council for Scholarship (CSC) in 2010 and got MS and PhD degree at the University of Arizona, one of the three best optics research institutes in the United States. During his Ph.D. period, he devoted himself to the research of illumination engineering, free-form surface optical design, related optical system development, and optical testing. After graduation, he worked as an Optical Engineer for North American Lighting Inc. and CREE Inc. in the United States. Since 2016, he currently serves as an assistant professor at the School of Optical and Electronic Information at Huazhong University of Science and Technology.
