基于Origin的光栅衍射仿真实验

Simulation Experiment of Grating Diffraction Based on Origin

依据多缝夫琅禾费衍射的基本原理,用Origin软件对光栅衍射现象进行了模拟仿真。通过改变入射光的入射角以及光栅常数等参量,得出了在不同条件下的衍射谱线特征。仿真实现过程具有良好的灵活性和可控性,仿真图像细致逼真,能够展现出具体实验中不容易观察到的光学现象和状态,其结果和方法在光学实验教学中具有应用价值。

According to Fraunhofer diffraction theory,using Origin software,we have simulated grating diffraction.By changing the incident angle,grating constant and so on,we can get a variety of diffraction line under different conditions.The simulation implementation process has better flexibility and controllability,The simulation images are detailed and realistic,which can demonstrate optical phenomena and conditions that are not easily observed in specific experiments,the results and methods have application value in optical experiment teaching.
