Yu Jianjie, male, Zhejiang, was born in 1980, entered the Department of Electronic Science and technology of Harbin Institute of Technology in 1998, and received a bachelor's degree in engineering, a master of Engineering in optical engineering, and a Ph. D. in physics electronics. In 2009, he stayed in school. He was promoted to associate professor in 2012 and transferred from Harbin Institute of Technology in May 2014. During the period of Harbin Institute of Technology, he started his research and engineering projects on free space laser communication technology from his undergraduate thesis. In 2014, he was transferred to Zhejiang University, first engaged in the research and development of photoelectric instruments. In 2016, the team began to study the new technologies related to free space laser communication and undertake relevant research projects. At present, the research work of the laboratory mainly focuses on the field of optical and electrical intersecting, including the overall design of the photoelectric system, the new aim acquisition and tracking technology, the adaptive optics technology, the weak photoelectric signal processing，etc..
