摘要

在迈克耳孙干涉测波长实验中,计数干涉圆环的吞吐数量历来是实验者头疼之事,本文开发了一种基于智能手机的自动计数软件系统.该软件通过智能手机自带摄像头采集干涉环图像,经滤波分析自动计算干涉圆环吞吐数.该系统操作简单,计数精度可以达到0.5 环,大大提高了测量准确度.随着智能手机的普及应用,该系统具有广阔的应用前景.

Abstract

Counting the number of interference fringes has always been a headache in the Michelson interferometer experiment for measuring the wavelength of He-Ne laser.In this paper,we introduce the automatic counting software system based on smartphone.The software comes with a smartphone camera to capture the interference fringe image.We use the Fourier transform filter analysis to calculate the number of fringe throughout automatically.The system is simple to   operate and has a counting accuracy of up to 0.5 fringe,which greatly improves the measurement accuracy.With the popularity of smartphone applications,the system has broad application prospects.
