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

In the experiment of determining the VolumePhase Holographic Grating's parameters, the error of the result is not over 1%, so it demonstrates the metrology's validity and feasibility.
The measuring device has the advantages of making full use of a fixed volumephase balance pool and adjusting the pressure of the whole system through the externally connected container.
