通过对计算机模拟漫射体产生离面倾斜的时变散斑图，计算其均方根误差值，进行了验证。
The out-of-plane tilting speckle interferogram is computer-simulated and the RMS phase error is calculated to verify reliability.
最后在模拟测试之下，利用最大概似估计法求得各参数的误差、均方根误差、参数之上下界限以及涵盖。
Simulation results show that the maximum likelihood estimates perform well in most cases in terms of the mean bias, errors in the root mean square and the coverage rate.
