Some applications of CCD rapid-changing-frequency high-speed videography system

"Model 3H-2100 CCD High Speed Videography System" is developed by Zhejiang University recently. This system has high videographic frequency, strong "freezing" ability, large range of videographic parameters that can be controlled according to needs. The problems of measuring moving object have been solved with quick, online, real-time and automatic method by this system. Principles of the system are introduced briefly; Successful experiments of the system such as flying bullet test, target hitting test, rotation test are illustrated; Problems of choosing videographic parameters, searching factors influencing image resolution and measuring presicion are discussed. Potential application fields are also introduced in this paper. Keywords: High speed videography, video graphic frequency, freezing ability, bullet testing, rotation testing, image processing
