scattering problem in periodic structural mediums often discussed in the theory and applications of modern micro-optics, where periodic structural mediums are often called diffraction gratings.───在现代光学理论及应用中，经常要讨论周期结构介质中的散射问题，其中周期结构通常被称为衍射光栅。

mechanism of grating generation and the potential application of the gratings in integrated optics are discussed.───讨论了光栅的形成机制及其在集成光学中潜在的应用。

Based on flat field diffraction gratings and array detectors, the optics and structures of a Shortwave Infrared (SWIR) field spectroradiometer were designed.───基于平场凹面光栅分光和线列阵探测器探测的最新设计方案，进行了短波红外波段地物光谱仪的光机设计。
