实验中制作出了高衍射效率和信噪比的体积全息光栅和反射全息图。
The holographic volume gratings and reflection holograms having high diffraction efficiencies and signal noise ratio are also fabricated in experiment.
一束电子波衍射的方式，同光波从一个反射光栅上弹回的方式完全类似，这真是不可思议。
Amazingly enough, a beam of electrons had thus been diffracted in a manner completely analogous to a light wave bouncing off a reflection grating.
其次分析影响相位光栅对准标记衍射效率的主要因素槽深、占空比和反射率；
Alignment signal of phase grating alignment mark and the factors of influece of alignment signal are analysed secondly;
沿光纤光轴传输到光纤倾斜端面上的光将被全反射，同时被光栅衍射。
The light propagating along the axis of the fiber incident on the angled end will be totally reflected and diffracted.
