摘　　要： 采用Labview图形化编程模拟光栅衍射光谱,可以非常方便地调节光栅常数、入射光波长、总缝数、单缝宽度、入射方向等参数,观察到衍射光强分布的相应变化,展示光栅光谱的全貌,便于分析衍射光栅的特点。这种方法作为辅助教学手段,有助于学生更加深刻地理解光栅衍射的特征和规律,提高教学质量。 The distribution of optical strength of diffractive gratings and characteristic of chart line was acquired based on graphical program with Labview software.The diffraction fringes of change will be observed by adjusting the parameter of grating constant,incident wavelength,the number of slit,the width of single slit and incident direction,etc.The panorama of grating spectrum can be showed in this simulation experiment and makes easy to analyze the characteristic of the grating.As an auxiliary teaching means,it helps to profoundly understand the diffraction phenomenon and characteristics.
