摘　　要：为了精确、便捷地实现迈克尔逊干涉条纹的自动计数,提出了一种结合PASCO科学工作室和Matlab软件编程的计数方法。该方法利用PASCO科学工作室的高性能光传感器实时地采集迈克尔逊干涉中心条纹,再通过简单的Matlab编程来实现干涉条纹的精确计数,克服了现有的电路计数方式调试麻烦和CCD计数方式图像处理难度大的缺点。实验结果表明,提出的干涉条纹计数方法不但精确直观,而且简单实用。A novel method was introduced to count the Michelson interference fringe based on the platform of PASCO science workshop.The software is used to sample fringe,then counting is completed by simply Matlab program.This improved method overcomes the disadvantages of circuit method and CCD counting method.The experiment can be carried out more conveniently and more visual.It is shown that the simply fringe counting method has high precision.
