同时，本文还计算出了这几种参数的误差容限，这对体积相位全息光栅的实际制作具有指导作用。

Furthermore, the paper offers the error limited of these parameters and they are good to guide practical fabrication of the volume phase holographic grating.

在反演体积相位全息光栅参量的实验中，反演出的光栅参量与真值的误差不超过1%。证明了该法的正确性和可行性。

In the experiment of determining the Volume Phase Holographic Grating's parameters, the error of the result is not over 1%, so it demonstrates the metrology's validity and feasibility.
