Main research directions and achievements of Lijing Town

Since 1964, he has been engaged in the research of transient optical imaging technology and photonics: he has developed the first internationally advanced ultra-high-speed waiting framing camera in China, the first rotating mirror synchronous ultra-high-speed framing camera with a shooting frequency of 20 million frames per second in China, the first beryllium rotating mirror ultra-high-speed scanning camera in China, and the first generation airborne integrated lattice head intermittent high-speed camera in China. The development series of high-speed photographic measuring instrument for large-scale rocket launch drift in China was launched, which made important contributions to major national scientific research projects such as "two bombs" test, large-scale rocket launch and "Shenzhou" series spacecraft launch. At the same time, the concept and formation mechanism of ultra-high-speed photography, holographic coherent shutter technology, grating coding technology and dispersion coding technology are put forward, and ultra-high-speed photography of trillions of frames per second is realized for the first time in the world. As the project leader, he won 6 national awards, 9 provincial and ministerial awards and 2 invention patents; Six books have been published (including three major compilations), among which "Optical Manual" and "Laser Measurement" have great influence; 120 paper. During my stay in Shenzhen University, I completed six national scientific research projects and won the second prize of National Technological Invention Award 1, the first prize of Guangdong Science and Technology Award 1, the nomination prize of the 4th National Book Award 1, and the second prizes of "National Excellent Science and Technology Books" and "Science and Technology Progress (Science and Technology Monographs)" 1. Awarded the "20th Century Achievement Award" by Cambridge International Biography Center.

On March 8th, 20 12, the research team led by Professor Li Jingzhen of our school, supported by the National Natural Science Foundation of China, Shenzhen Municipal Government and Shenzhen University, successfully developed the SSF ultrafast process multi-frame scanning simultaneous imaging recorder, and passed the appraisal in Xi 'an. This achievement was jointly completed by Shenzhen University, Xi 'an Institute of Optics and Fine Mechanics of China Academy of Sciences and Institute of Fluid Physics of China Academy of Engineering Physics.

The appraisal meeting was organized by the Guangdong Provincial Department of Education and entrusted by the Guangdong Provincial Department of Science and Technology and the National Natural Science Foundation of China. The appraisal committee is headed by Professor Jin Guofan, an academician of China Academy of Engineering, and composed of several experts including Zhou Bingkun, Xue Yongqi, Lin Zunqi, Wu, Li, Shen Xubang and Wei Ziqing, academicians of China Academy of Engineering.

The appraisal committee believes that SSF ultrafast process framing scanning simultaneous imaging recorder is a precise scientific instrument for studying high-speed passing process, which can provide temporal and spatial information and optical information of transient phenomena, is a key optical test equipment for studying detonation physics and shock wave physics, and is also an indispensable research equipment for high-density energy transfer, high-temperature plasma physics, high-voltage discharge, jet fuel chemistry and hypersonic wind tunnel experiments. The imaging recorder has advanced indexes and stable and reliable performance. It is an advanced equipment with original ideas and technology, and its overall performance index is in the leading position in the world compared with similar foreign instruments.

According to the appraisal opinion, the instrument has many original innovations in principle and technical application. The main technical performance of the instrument, including the inherent spatial resolution of framing imaging system in time and space, the spatio-temporal information rate of high-speed photography, the principle error of adjacent framing time and the maximum scanning speed of scanning imaging system, is superior to the international advanced level of similar instruments. At the same time, it breaks through the conclusion that the multi-frame scanning simultaneous imaging recording system can not achieve the high spatial resolution of a single-function ultra-high-speed camera.

It is understood that the research team led by Professor Li Jingzhen of Shenzhen University has been innovative and persistent for eight years, and finally won the "Crown Pearl" in the field of ultra-high-speed rotating mirror imaging, which is another important achievement after winning the second prize of national invention in 2005.
