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.

结果：所建的5个模型对验证集样品水分含量的预测值与实测值的相关系数均在0.90以上，预测误差均方根（RMSEP）均在0.05以下。

Result:The coefficients of correlation of inner cross validation and external validation are both above 0.90, and the RMSECV and RMSEP are both below 0.05.
