Abstract
In practical applications, it is possible to acquire multidirectional interferometric data of different instants. In such cases, refractive-index fileds can be reconstructed based on the multidirectional interferometric data of two consecutive times. The advantages of using the interferometric data of different instants include: more a priori information and knowledge about refractive-index fields can be incorporated in reconstruction and the problem of sovling velociety, temperature and pressure fields will be simplified. In this paper. An iterative direct 3D reconstruction algorithm from the interferometric data of two consecutive times is presented. The problem of calculating physical fields of fluid is discussed. The experimental results are also provided.
