Academic Areas: Optical measurement

Prof. zhao graduated from zhejiang university with a bachelor's degree in 1984, graduated from Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences with a master's degree in 1987,and graduated from Huazhong University of science and technology with a doctor's degree in 1997. Since then he has been working in the field of optical precision measurement. he researched on the laser triangulation rangefinder which can be widely used in industry for Non contact measurement of geometric parameter. A relevant laser thickness gauge has been developed which can be used in Strip production line such as sheet metal, Galvanized sheet and Cell membrane Plating line. Prof Zhao Put forward the application of non-diffraction beam technology in the field of optical measurement. By using the geometric center of the circular spot ring instead of the ordinary spot energy center, the accuracy of the spot center is improved Greatly. This has become a  basic optical precise measuring method which has been realized in straightness measurement, imaging for large depth of field, Space attitude angle and Space coordinate measurement. Prof. zhao taught Undergraduate course “Laser measurement technology and instruments” and graduate course “Photoelectric detection technology”
