Abstract
Visualization of the high flow velocity using the high speed video system or the AOM are usually carried out . But these systems are not so good as the normal CCDcamera and the strobe in respect to sensitivity, resolving power and brightness.
In this study, a system was developed to visualize the high flow velocity, which consists of the strobe with delay control and the normal CCDcamera . And the method of particle tracking was constructed to compare the arrangement of particle of two images . This method was combined with the fluorescence particle, that was tried measuring of two phase flow of air and liquid.
