REVIEW OF THE σTH NATIONAL CONGRESS ON HSPP

The 6th National Congress on HSPP was held in Xian, Shaanxi on 20~22 December 1990. A hundred participants have presented and 102 technical articles have reported on the sessions.The developments of highspeed cameras and optical techniques which were showed in the meetings are introduced and reviewed briefly in this paper. Opto-mechanical cameras have also been made some progress in reducing weight of cameras and getting more suitable for using in many special kinds of fields. There is a new idea of optical fibre camera presented in discussion. It was reported that time resolution of streak image tube camera has reached 300PS and shortest exposure time of the framing one is 100ps both experimentally. An optical oscilloscope with 10GHZ has been made recently.Applications of highspeed optical techniques in industry, biological engineering, high-speed impact, trajectory and detonation were strongly concerned by participants. Realtime imaging system, laser speckle and Moire method, dynamic photomicrography, holography, flash xray photography and underwater photography are used many achievements have been made in the fields mentioned above.
