An academic report was presented by Xue Yongqi, member of CAS, expert in infrared remote sensing technology, researcher at Shanghai Institute of Technical Physics. This was Xue's well-planned trip to USTC accompanied by Wang Jianyu, head of Shanghai Institute of Technical Physics and dean of the Electronics Science and Technology Department. This visit also marked a milestone in the collaboration between SIST and SITP. Prof. Xu Wu, vice-clerk of the party committee and the vice-president extended the warm welcome to Dean Wang and Academician Xue. Wang reviewed the undergoing IC engineering collaborative projects between the two institutes. For the disciplinary construction, Wang suggested that the projects applied under the name of the two institutes should be the starting point for the application of national fund and resources, and a full support should be drawn from USTC.

An academic lecture entitled "The Optical Imaging Techniques in the Earth Observations" impressed the faculty and students of SIST. This lecture was moderated by Prof. Fu Zhongqian, executive dean of SIST. In his lecture, Xue gave a systematic introduction of the optical imaging techniques, including the Satellite-bone and airborne spectral scanners, PHI, and Hyperspectral scanners. The audiences were firmly attracted by his vivid interpretation, demonstrations and true-to-life charts and images. After the report, Xue extended his understanding on some questions of general interest.

In addition, Xue had an informal discussion with some of the faculties in this department. In recalling his student and career experiences, he encouraged the young faculty to seize every opportunity and work harder so as to contribute more to the country and to realize their own values.

Biography of Academician Xue Yongqi

Academician Xue Yongqi is infrared and remote sensing technique specialist, born in Zhangjia Gang, Jiangsu Province. He graduated from the Physics Department of the East China Normal University with Bachelor's degree in 1959 and became a research professor of the Shanghai Institute of Technical Physics, Chinese Academy of Sciences. Engaged in the research of multi-spectral and imaging spectral techniques, he has provided several types of advanced remote sensing means for the setting-up of China's operational airborne remote sensing system and promoted the application of remote sensing technique in China. Up to now he has successfully developed multi-spectral scanners, imaging spectrometer, super-spectral imaging system one after another. Remarkable results have been obtained in the applications of airborne remote sensing instrument in hydrology, geology, archaeology, environment pollution monitoring and etc. Being the first in China to develop the three–dimension imaging remote sensing technique, he suggested to combine the scanning spectral imaging with laser scanning ranging and realized fast forming digital elevation model without ground control points and geo-reference images which are particularly suitable for beach, desert, grasslands, islands and etc where are poor transport facilities.
