基于LabVIEW的牛顿环实验动态仿真

摘要

虚拟仪器是现代仪器的一个主要发展方向,也是实验和教学的重要补充方式.本文基于LabVIEW设计了虚拟牛顿环实验演示仪,一方面,利用LabVIEW强大的功能模拟了牛顿环实验的光强分布图,使虚拟仪器的整个实验仿真过程动态、直观、形象,可直观地分析各参数对干涉结果的影响；另一方面,虚拟仪器的使用不受环境的限制,可为理论教学和实验教学过程所用,从而加强学生对光干涉理论的理解.%Virtual instrument is a major development of instrument,and is an important complementary for experiments and teaching.The distribution of light intensity in Newton ring experiment is simulated dynamically based on LabVIEW in this paper.On the one hand,the influence of parameters on the interference fringe is shown clearly,making the entire process of simulation vivid.One the other hand,the simulation of Newton ring experiment,which is not subject to environmental constraints,can be used for theoretical teaching,facilitating students' understanding of the optical theory.
