通过计算机模拟研究,考查了Radon变换迭代法用于光学干涉层析计量含有遮挡物三维折射率场的重建精度。作为一个应用实例,计算了某一截面的气体温度分布,并与热电偶测量的值进行了比较。

In this paper, the reconstruction precision of Radon transform iteration, which is used in interferometric tomography for 3-D refractive index fields with an opaque object, has been studied by computer simulation. As an example, the method has been used to reconstruct the hot gas temperature fields,and the results are compared with thermocouple measurements.
