Jiang Yu 1966 was born in Pinghu, Zhejiang Province on May 9th. My mother, who used to be a teacher, gave her son all her love when she was 38 years old. His first education was received from his mother when he was four or five years old. Because his mother taught him the first and second grades of primary school, young Jiang went directly to the third grade when he was six years old.

His interest in science began in junior high school. Pinghu, a small town in Zhejiang at that time, was located in Hangjiahu Plain, close to Shanghai, but it was still quite secluded. I came across some juvenile books at that time, such as "Middle School Students" and "Enlightened Teenagers", among which the content about natural science deeply attracted Jiang, and he tried his best to collect such books. Once he finds one, he is like a treasure and greedily reads it. Although a lot of content is incomprehensible, the mystery of nature has pulled him over.

His high school is in Shanghai Fudan Middle School. Fudan Middle School has a group of high-level teachers and a good learning atmosphere. Several teachers gave wonderful and enlightening lectures. Under the guidance of the teacher, he was even more inspired by the pursuit of knowledge. In several winter and summer vacations, he did the exercises in several famous textbooks of geometry, algebra and trigonometry at that time. At the same time, he also studies extracurricular knowledge hard. At that time, it was a great pleasure for him to read books on holidays in the streets where several old bookstores were concentrated in Shanghai. What attracted him most at that time was Science Illustrated, which introduced a lot of new knowledge in simple terms. This deepened his keen interest in science.

Jiang spent his college life in Harbin Institute of Technology. In response to the call, he chose the most difficult major-casting technology and equipment. At that time, Harbin Institute of Technology studied the Soviet model and followed the Soviet teaching system. It is also difficult for him to make a comprehensive evaluation of the advantages and disadvantages of this system, but two points are still very useful. First, there are many practical opportunities such as curriculum design, graduation design and internship, and I have already had considerable engineering practice ability when I left school. His first job after graduation was to design a 1000t large-scale die-casting equipment. In less than half a year, two or three young men who have just left school, under the guidance of old comrades, have basically completed nearly a thousand drawings of a large-scale equipment, which cannot but be attributed to his engineering training in the university. Another feature is that all major topics are oral exams. Each student enters the examination room and draws out a paper consisting of three or four questions, which covers a wide range. Every test paper is different. After more than half an hour of preparation, he will tell the examiner the answer and be further questioned by the teacher. This has at least two advantages. One is to exercise his comprehensive expression ability on a scientific and technological problem, and the other is that the concept must be clear, otherwise it will be exposed under the teacher's questioning, and he will make every effort to master what he has learned. Mastering the essence of physics and achieving mastery through a comprehensive study has become an important principle in his decades of work.

1936 was born in pinghu city, Zhejiang Province on May 9th. Expert in optical technology. 1958 graduated from the mechanical technology department of Harbin Institute of Technology. He has served as an intern researcher in Changchun Institute of Machinery of China Academy of Sciences, an intern researcher and assistant researcher in Changchun Institute of Optics and Mechanics of China Academy of Sciences, an assistant researcher, associate researcher and researcher in Institute of Optoelectronic Technology of Chinese Academy of Sciences, deputy director of the Institute and director of the academic committee. At present, he is the director and researcher of the adaptive optics research office of the institute, and the deputy director of the State Key Laboratory of Atmospheric Optics of the 863 Program. 1995 was elected as an academician of China Academy of Engineering.

In his early years, Mr. Jiang engaged in the research of large-scale optical measuring equipment and made pioneering contributions to the theory and technology of precision shafting and fixed optical measuring system. 1979, the research direction of adaptive optics is first developed in China, a set of basic technologies has been established, and several generations of systems with international advanced level have been developed. He has made great contributions to adaptive optics and beam control: "19 unit wavefront correction system" successfully developed for Shen Guang high-power laser device is the first practical device of its kind in the world; Successfully developed "2 1 unit adaptive optical system", making China the third country in the world to realize real-time correction imaging of star targets; The "2. 16m telescope infrared adaptive optical observation system" successfully developed in cooperation with Beijing Observatory has enabled China to have one of the few practical adaptive optical observation systems in the near infrared band. 37-unit and 6 1 unit adaptive optical systems have respectively compensated for the horizontal and oblique atmospheric turbulence, and obtained the correction effect that has never been reported in the world, making China's research in the field of adaptive optics in the forefront of the world.
