Abstract

This paper presents a technique of high speed interferometric photography for measuring time and space feature of transient flow field, that is single-path and multi-path high speed interferometric photography for transient flow field,and it discusses the principle of interferometric tomography and the method of time-serial high speed interferometric photography. By using this method and principle,the time-serial interferograms of shock wave in forming process from real rocket engine can be obtained, and three-dimensional temperature distribution about asymmetric flame can be calculated quantitatively.
