This paper discusses the basic theory of transient laser holographic interferometry and the key technologies to be solved in engineering surveying. The application examples of several kinds of transient holographic interferometry are briefly introduced. The transient laser holographic interferometry Measurement of test equipment made a detailed introduction. The article is divided into four parts: 1) the physical process of off-axis light holography and a brief mathematical description; 2) the key technologies of transient laser holographic interferometry; 3) introduce several typical test equipment; 4) discussion.
