摘要
本文通过计算机模拟研究 ,利用气体温度场的先验知识 ,考查了用光束偏转层析技术重建三维温度场的基于卷积反投影的三种Radon变换迭代法。作为一个应用实例 ,测试了某截面上的气体温度分布 。
In this paper,the reconstruction precision of three methods of Radon transform iteration based on convolution backprojection,which are used for reconstructing 3 D temperature fields by beam deflection optical tomography,have been studied by computer simulation with the prior knowledge of these fields.As an example,the method has been used to reconstruct the hot gas temperature fields,and the results are compared with thermocouple measurements.
