achievements in scientific research

Hou Xun is engaged in the research of transient optics technology. As the main participant, academic leader and project leader, he personally participated in the development of a series of electro-optical and electro-optical high-speed cameras.

The development of 1985 series ultra-high-speed instantaneous field observation equipment, together with other shooting range observation instruments, won the national special prize of scientific and technological progress "Dynamic optical observation and measurement technology in modern national defense test". Hou Xun won the individual award, ranking fifth.

In order to further develop China's transient optical technology and promote the study of ultrafast phenomena, he initiated and organized the application for the project of "State Key Laboratory of Transient Optical Technology" and achieved success. 199 1 year, organized an application for the establishment of "femtosecond laser technology and ultrafast process research" and the "Eighth Five-Year Plan" climbing project, and was hired as the chief scientist of the project by the State Science and Technology Commission after approval. The project consists of femtosecond laser technology, ultrafast measurement technology and ultrafast process research, and is undertaken by relevant scientific and technical personnel of six universities. It has been completed very well: 1996 was rated as a class when it passed the acceptance of the State Science and Technology Commission. Since 1997, as one of the conveners of the expert group of the "Ninth Five-Year Plan" pre-selected project, he has undertaken the organization and research of ultrafast process research. 200 1, and the project is hired as grade a.

In addition, Hou Xun successfully developed a four-stage image intensifier coupled with magnetically focused mica in 1970s. Transmission GaAs cathode and field-assisted photocathode have been successfully developed in China. In the early 1980s, a palladium-silver-cesium oxide cathode with high long wave response, low surface resistance and good stability was invented. China has successfully developed a double proximity focusing image intensifier; A combined infrared cathode made of electron trap material was invented. Invented a new high-efficiency X-ray photocathode and obtained a Chinese and American invention patent; 1990, a microchannel plate X-ray image intensifier with a diameter of 100 mm was successfully developed. At that time, it was leading at home and abroad, patented by China. In order to solve the problem of detecting dark, small, fast and multi-targets in conventional weapon shooting range, he proposed the method of using pulsed laser illumination, interference filter to suppress background and image intensifier to enhance the target image, and successfully developed a new generation of optical measuring equipment for shooting range in China, which won the second prize of National Science and Technology Progress Award 1992. He attached great importance to the transformation of scientific research achievements, and once presided over the design and manufacture of a complete set of image intensifier manufacturing equipment, earning foreign exchange through export 1, 9 1, 000 USD.

Since he was hired as a professor in 2000, he and Professor Wu Hongcai have co-chaired the 985 project "Massive Information Technology", led the research work on ultra-high-density optical storage of information, passive devices for optical communication, low-loss organic optical fiber, and established the "Shaanxi Key Laboratory of Information Photonics Technology".

1984 was awarded the title of "Young and Middle-aged Expert with Outstanding Contribution" by the Ministry of Personnel.

1989 was awarded the title of "National Advanced Worker" by the State Council.

199 1 was elected as an academician of China Academy of Sciences (now renamed as an academician).

In 2002, he was hired as a member of the Advisory Expert Committee of the Department of Mathematics and Physics of the National Natural Science Foundation of China.

In 2002, he was hired as a special member of the second decision-making advisory Committee of Shaanxi Province.

At present, he is the executive director of chinese optical society, the director of high-speed photography and photonics professional committee, the vice chairman of Shaanxi Association for Science and Technology, the chairman of Shaanxi Physical Society and the director of Chinese Physical Society.

Job position

At present, he is a director of Chinese Physical Society, executive director of chinese optical society, vice chairman of Shaanxi Science and Technology Association, chairman of Shaanxi Physical Society, adjunct professor of China University of Science and Technology, dean of School of Electronics and Information Engineering of Anjiao University, double-employed professor of Northwest University, consultant professor of Beijing Institute of Technology and adjunct professor of South China Normal University. In June, 2000, Academician Hou Xun was appointed as a professor in the Physics Department of Henan University.

Academician Hou Xun personally participated in the development of a series of electro-optical and photoelectric high-speed cameras, mainly including: China's first Kerr box high-speed camera, TV-image converter high-speed camera and fiber-optic image converter nanosecond scanning camera, visible light picosecond scanning camera, X-ray picosecond scanning camera, four-channel nanosecond image converter framing camera and infrared picosecond image converter framing camera. The theoretical analysis and derived calculation formula of double wedge Kerr box are two years earlier than the results published internationally. High-speed camera with image converter integrates modern physics, optoelectronics, precision machinery, electronics and computer technology, which meets the urgent needs of the development of modern science and technology in China. Together with other observation instruments, it won the 1985 national special prize for scientific and technological progress. Hou Xun won the individual award, ranking fifth. The successful development of the above-mentioned series of ultra-high-speed transient observation equipment has improved the time resolution of ultra-fast phenomenon research in China from microsecond level to picosecond level, which has increased by six orders of magnitude, and the response band has changed from infrared coverage to soft X-ray, catching up with the international advanced level. These achievements won the national or China Academy of Sciences special prize for scientific and technological progress and the first, second and third prizes respectively. Hou Xun himself, after Academician Gong Zutong and Academician Wang Daheng, became the China national representative of the 1990 International Conference on High-speed Photography and Photonics. Since 1978, he has participated in or led a delegation to the international academic conference on high-speed photography and photonics for many times. As the chairman of the project committee, he assisted Academician Wang Daheng in organizing the 18 international conference on high-speed photography and photonics held in Xi 'an in 1988, which was a complete success.
