Multidirectional interferometric data of an inhomogeneous phase object are obtained by double exposure reflection type holography. The evaluation of the interferograms for a computerized tomographic reconstruction of the local index of refraction by the convolution method is performed with subfringe resolution. For testing purposes the phase object is made by careful modeling of a convective heat flow in air. The reconstructed refractive index field is converted into a temperature distribution and is compared with independently measured temperature values, thus providing a strict examination of the quality of the tomograms.
通过双曝光反射型全息术获得非均匀相位物体的多方向干涉测量数据。采用亚条纹分辨率，通过卷积法对干涉图进行评估，以实现对局部折射率的计算机断层重建。为了测试目的，通过对空气中的对流热流进行精细建模来制作相位物体。将重建的折射率场转换为温度分布，并与独立测量的温度值进行比较，从而对断层图像的质量进行严格检验。
