The Laser Radar Center of Remote Sensing of Atmosphere (LRCRSA), funded with over 2 million RMB by Xi'an University of Technology, was established in Sep. 2005. The main role of LRCRSA is to meet with the services of teaching and science researches, to provide the impetus for the development of the academic discipline's construction, to expand new direction of the academic subjects, and to train a number of high-level specialty talents in the field of laser remote sensing. LRCRSA has been capable of studying the main atmospheric parameters (atmospheric temperature, humidity, wind speed and direction, etc) and the optical properties of atmosphere (aerosol extinction and backscattering coefficients, optical thickness, visibility, particle-shaped matters such as clouds and aerosols, etc) with laser radar (lidar) technique. Now, LRCRSA are devoted to the research of the basic theory for new-type laser lidar remote sensing and practical measuring system. Especially LRCRSA are focused on the study of the development of high-efficiency and miniaturization type of lidar system in the field of measurement of temperature and humidity in day-time with high precision, and are making efforts to develop a lidar system with high-efficiency, multi-function, multi-wavelength and its corresponding practicality system. Professor Dengxin Hua, the principal of LRCRSA, has engaged in the field of basic theory of remote sensing of atmosphere and related products developments in Japan for over 10 years. The first multi-function laser radar system in the world developed by Prof. Hua aroused peoples' attention and had so tremendous influence in the field of environmental and meteorological study that it was then reported by Japanese Economic News, Japanese Industrial Journal and MX TV station of Tokyo. With his efforts for many years, his achievements have been published by several top-ranking optical Journals such as Optics Letters, Applied Optics and so on. LRCRSA has been provided with many equipments, which include high power single frequency pulsed Nd:YAG laser, telescope receiver, optical components and detectors, and other auxiliary apparatus necessary to do lidar researches. The research of LRCRSA, not only keeps up with the tendency of international laser radar detecting technology but also develops kinds of international cooperation. At all times, LRCRSA are dedicated to related updated researches, and also have founded a long-term academic communication and cooperation study with several companies and universities overseas. In particular, Professor Takao Kobayshi, a famous international lidar expert, has been invited and employed to be an adjunct professor in Xi'an University of Technology in Oct.2005. Moreover, LRCRSA is also constantly to invite many well-known experts internal or external to give lectures.
