Paper Abstract

Optical Computerized Tomography is a technique which is famous for real-time, stable and non-contact characteristics in various flow fields' diagnosis. As a result, it shows superiorities in many domains, including the aerospace survey and the measurement of the thermo physical parameters. Due to most of the traditional reconstruction methods of OCT are based on 2-D Radon Transform, they are pseudo three-dimensional in essence. That is to say, the flow field is divided into several parallel slices firstly, and then, the stack of tomogram slices is subsequently used to compute the 3-D representation. However, all the flow fields own real three-dimensional character. Therefore, in this paper, based on the 3-D Radon Transform, the optical interferometry is studied on the model of the volume CT. Meanwhile, the sufficiency condition of accurate reconstruction is studied. Besides, the transform reconstruction algorithm for volume OCT is also presented and verified by simulated experiments. In a word, this study will be better to visualize and display flow fields.
