基于LabVIEW的迈克尔逊干涉仪虚拟仿真实验系统设计

迈克尔逊干涉仪是一种重要的精密光学实验仪器,可应用于多种实验之中,是大学物理的必学内容.但由于器材数量、场地等原因,学生往往不能很好地掌握迈克尔逊干涉仪相关的知识.根据测量光波波长、介质折射率和微小位移等实验原理及教学要求,开发出一种基于LabVIEW的迈克尔逊干涉仪虚拟仿真实验系统.该系统不仅可用于学习迈克尔逊干涉仪的工作原理以及相关实验的原理,而且可演示这3个实验的基本实验操作以及进行实时数据处理.基于LabVIEW的迈克尔逊干涉仪虚拟仿真实验系统还具有界面简洁、交互性强等优点,能有效激发学生的学习兴趣,从而提升课堂教学效果.

On a Virtual Simulation Experiment System of Michelsom Interferomer Based on LabVIEW

One of important precision optical experimental instruments is the Michelson interferometer, which can be used in a variety of experiments and needs to be mastered by students in college physics course. However, due to the lack of equipment, venues, and so on, students can not master the knowledge of Michelson interferometer well. According to the teaching requirements of measuring laser wavelength, the refractive index of medium and microdisplacement, a new virtual simulation experiment system of Michelson interferometer based on graphical programming language LabVIEW have been developed. The system can be used not only to learn the working principle of the Michelson interferometer and the principle of related experiments, but also to demonstrate the basic experimental operations of the above three experiments and to perform real-time data processing. Moreover, the virtual experiment system of Michelson interferometer based on LabVIEW also has the advantages of a simple interface, strong interaction, and so on, which can effectively stimulate students'' interest in learning and enhance the effect of classroom teaching.
