摘要
用傅里叶光学来解决周期性结构的衍射问题既准确方便又容易理解。从研究透射闪耀光栅的透射函数及反射闪耀光栅的反射函数出发 ,利用傅里叶光学原理 ,从理论上分析了闪耀光栅衍射图样的复振幅和光强分布与闪耀角及波长的关系 ,并利用计算机进行了模拟计算。计算的效率曲线与实际刻划的闪耀光栅效率曲线吻合的很好。
It is very convenient to analyze the diffraction of the periodic structure with Fourier optics. By studying the transmission function of the transmission grating and the reflection function of the reflection grating, the relationship between the intensity of the diffraction picture and the blaze angle is analyzed. The diffraction intensity is calculated with computer. The result obtained is proved to be correct.
