基于LabVIEW的干涉虚拟实验研究

Research on interference virtual experiment based on LabVIEW

根据光的双缝干涉实验理论,利用Lab VIEW编写程序对双缝干涉实验进行模拟,描述了双缝干涉的图样和光强分布曲线,并计算了条纹间距和对比度,直观地展示了双缝干涉这一物理现象,同时设置了初始条件修改模块,可以清晰地显示不同条件下的干涉现象,为双缝干涉的理论与实验提供了有力的支持。

According to the theory of the double slit interference experiment, the dissertation simulates the double slit interference experiment by LabVIEW program. It describes the pattern and the light intensity distribution curve of the double slit interference, intuitively show the physical phenomenon of double slit interference. At the same time, the initial condition modification module is set up, which can clearly show the interference phenomenon under different conditions. It provides a strong support for the theory and experiment of the double slit interference.
