摘　　要：光栅是利用多缝衍射原理使光发生色散的光学元件.广义的衍射光栅可分为透射光栅和反射光栅.近些年来,随着科学技术的进步和工业生产技术的发展,出现了光纤光栅、阵列波导光栅及全息光栅等新型光栅,这类新型光栅的产生同样也推动了科学技术和工业生产的发展.此外,光栅在物理教学和实验室中也具有重要的应用.物理实验教学中可以利用透射光栅测量入射光的光波波长,并利用光的衍射效应得出所用光栅的光学参量等.首先概括了光栅的发展历史和应用,其次以“透射光栅测量光波波长”为着手点,重点介绍了透射光栅在物理实验教学中的应用.通过进行实验操作,计算了光栅的角色散度和分辨本领,对实验数据进行分类对比及归纳总结,进而得出了透射光栅的特性及普遍规律.Grating is an optical element that disperses light by the principle of multi-slit diffraction.Generalized diffraction gratings can be divided into transmission gratings and reflection gratings.In recent years,with the progress of science and technology and the development of industrial production technology,new gratings such as fiber grating,array waveguide grating and holographic grating have appeared,and the generation of such new gratings has also promoted the development of science and technology and industrial production.In addition,the grating also has important applications in physics teaching and laboratories.In physics experiment teaching,the transmission grating can be used to measure the wavelength of the incident light,and the optical parameters of the grating can be obtained by the diffraction effect of the light.This paper first introduces the development history and application of the grating,and then focuses on the application of transmission gratings in the laboratory,starting from“measuring the wavelength of light waves with transmission gratings”.Through experimental operations,the role divergence and discrimination ability of gratings are calculated,and the experimental data is classified,compared,and summarized.Finally,the characteristics and general laws of transmission gratings are obtained.
