摘要
光栅是一种折射率周期性变化的光学元件。最常用的光栅是由大量等宽、等间距的平行狭缝组成的，通常是在一块平面玻璃上用金刚石刻制、复制或用全息照相等方法制成。
光栅是一种重要的分光元件。光栅不仅适用于可见光波，还能用于红外和紫外光波，常被用来精确地测定光波长及进行光谱分析。以衍射光栅为色散元件组成的摄谱仪和单色仪是物质光谱分析的基本仪器之一。光栅衍射原理也是晶体X射线结构分析和近代频谱分析与光学信息处理的基础。

Abstract
The monochromatic light goes through the list and stitches the diffraction streak that afterwards may to take shape light and shapely alternate with ,Moreover may be through the streak breadth calculation light wave wavelength .Yet the use is alone stitched and is accurately surveyed is fully difficult ,For when stitches broad A is more great ,Streak clearance very narrowly is difficult to distinguish ；But stitches broad A hour ,Light powerful very much feeble ,Also not benefit the measurement ,The parallel in the way of much and so on intermission replace the broader list to stitch taking shape the raster in case carefully stitching ,Utilizes the raster may be exact the measurement light composes ,The physics being living heaves the fully significant sense in the test .
The appearance of the diffraction queen of the ray of this test by means of watch after the raster ,Comprehend the raster diffraction distinguishing feature ,Study to survey raster constant D ,Along with Gong's light either the atrium light feature composes string wavelength .
