本文通过计算机模拟运算,结合折射率场(温度场)的先验知识,考查了改进的共轭斜量迭代法用于全息干涉计量三维折射率场的重建精度及视角范围和数据噪声的影响,并介绍了一种抑制较大噪声的算法.作为一个应用实例,计算了某一截面火焰温度场的分布,并与热电偶测量的值进行了比较.

The reconstruction precision of an improved Conjugate-gradient iterative method, the effects of increased input data error and limited total viewing angle have been studied based on the knowledge of refractive index fields aid of computer simulations. As an example, the flame temperature fields were reconstructed, and the results are compared with thermocouple measurements.
