摘要
为了克服干涉法测金属线膨胀系数实验中人眼观测不准确的困难,利用Tracker软件的自动追踪功能,跟踪干涉条纹的明暗变化过程,实时描绘出干涉条纹的＂视觉亮度-时间＂（luma-t）变化曲线,并从中得到测温区间的干涉条纹变化数目N,从而更精确地求出光程差及金属线膨胀系数.
In order to overcome the difficulty of the observation of the human eye in the experiment of interferometry, in this paper, using the Tracker software of automatic tracking function, effectively track interference fringes of light and shade change process, real time picture of interference fringe “visual brightness time” （ luma t ） curve, and interference fringe change number, to calculate the optical path difference and metal linear expansion coefficient.
