Paper Abstract

This paper discusses the principles of tomographic reconstruction of three-dimensional temperature field from multi-directional interferometric data and presents a method of multi-directional image plane holographic interferometry, which solves the problems that interference fridges are not clear and viewing angle is small ( <90) in dif fused illumination holography. Using this method, an asymmetric three-dimensional temperature distribution in water has been measured. Furthermore, a multi-directional F-P interferometry is presented which has more practical value and can be used in dynamic whole process measurement.
