Abstract

By adopting a velocity-measuring system which consists of three techniques, i.e., the laser Doppler effect, the multiple-beam interferometry and high-speed photography with an image-converter tube we can accurately and precisely get the function of free sur-face velocity versus time in the non-contact measurement. As com-pared with the various present traditional methods to calculate average velocity by a streak camera with its probe or by means of reflection, our system can yield more accurate and reliable results. What's more, it has provided us with a new test means for those fundamental problems such as the disputable C-J hypothesis in detonics, detonation wave model in hydrodynamics as well as the theo-retical study of state-equation of detonation products.
