Paper Abstract

A new system of microcomputer-controlled stroboscope high speed photography has been developed recently. It has strong "frozen" ability, high photographic frequency, high accuracy of control time. Rapid-changing freqency of taking pictures and rapid-changing flash color are the most outstanding characters of this system. The Main technical parameters of this system, such as duration time of flashes, interflash time between flash and flash, flash numbers on one frame film and interframe time are controlled automatically by microcomputer. The synchronized operating of camera with stroboscope is also controlled by microcomputer. This system has been applied in multi-phase flow measurement and in physical training research. The results are successful and satisfactory. Usually, one flash is used to obtain clean "frozen" image, two-flashes can be used to get velocity data of moving object, and multiple-flashes is employed to gain the acceleration, track of moving object. While using multiple-times, multiple-color flashes, the moving tracks, velocity and acceleration vectors can be obtained.
