This paper develops a virtual simulation platform for Newtons rings interference experiment using LabVIEW software. The platform enables simulation of real Newtons rings interference experiments, allowing users to adjust parameters and visualize simulation results in real-time. Measurement experiments for liquid refractive index are conducted separately on both the real Newtons rings apparatus and the virtual simulation platform. A comparative analysis of the experimental results verify the accuracy of the virtual simulation platform. Additionally, the platform is employed to simulate and investigate the impact of changes in medium refractive index (N), incident light wavelength (λ), and curvature radius (R) on the characteristics of Newtons rings interference fringes, specifically analyzing fringe distribution patterns and light intensity features under different conditions. In theoretical and experimental teaching related to Newtons rings interference, this platform can directly be used for teaching demonstrations, effectively integrating theory with experiment and significantly enhancing teaching effectiveness.
