并在矩形光栅和正弦相位光栅的基础上,分析了液晶衍射光栅对入射光一级衍射情况及其衍射效率,得到了15°左右的衍射角,且衍射效率达到40%。
By changing the number of steps in one unit,the diffraction angle is changed.
结果表明,通过改变周期单元光栅电极数目而改变光栅常数,可以改变光衍射角度,一级衍射角度调节范围可达0°~10°;调节电极电压可以使特定级次衍射光效率达到90%以上,使该级次得到闪耀。
The most important approximation for Fraunhofer diffraction is that the observation point must be limited close to the axis,or the diffraction angle is not too large.
其中最重要的条件是观测点必须限制在傍轴附近,衍射角不能太大,否则得不到简单的解析公式,也就不能称之为夫琅和费衍射。
