Laser holographic and interference tomography of three-dimensional temperature field
This paper discussed the principle of tomographio reconstrnotion of 3-D temperature field from multi-directional interferogram and a mnlti-directional image plane holography is presented. It solves the problems of poor fringe clearness and small observation angle in diffused illumination holographic interferometry. 3-D temperature distribution has been measured using this method. Purthermore, a multidirectional F-P interferometry is put forward. It has more praotioal value and possesses real time characteristics and can be used to measure real transient field.
