倒格矢

最后我们将基于倒格矢理论的Talbot阵列照明器设计方法用于设计基于液晶空间光调制器的微透镜阵列，并和传统的微透镜阵列设计方法进行了比较。

Finally we use the method of designing Talbot array illuminator based on reciprocal vector theory design same microlens array based on LCD , and compare with the traditional method of designing microlens array .

本论文基于Talbot效应的倒格矢理论分析了几种常见的二维周期阵列物体的分数Talbot效应，设计了几种Talbot阵列照明器，并给出了计算机模拟结果与实验结果。

In this dissertation we analyse fractional Talbot effect of some simple period array objects based on reciprocal vector theory of Talbot effect and design some Talbot illuminators . Finally , some computer-simulated results and experimental results are also given .

同时，我们还发现，在正向倒格矢参与的情况下，非线性极化波的相速度会减小到Cerenkov上转换的相速阈值以下，从而调制型Cerenkov上转换会出现截止波长。

At the same time , we found that , in the condition of forward reciprocal vectors involved , the velocity of nonlinear polarization wave could be decreased down to the threshold of generating Cerenkov up-conversions , which resulted in the appearance of cutoff-wavelength in Cerenkov up-conversion processes .

考虑到真实超晶格系统的有限宽度会造成晶格的非周期性，我们修正了用来决定拉曼频移峰值位置的公式中的倒格矢一项。

The formula for determining the peak positions of Raman shifts of the strained superlattices is modified by considering the non-periodicity of the realistic superlattice caused by the finite size .
