摘　　要：迈克尔逊干涉仪常用于观察分振幅干涉条纹,但极少有人对条纹线型进行严格的分析讨论。笔者对点光源条件下迈克尔逊非定域干涉条纹的空间曲线方程进行了计算和分析,得到圆、椭圆、抛物线、双曲线和直线5种形式的条纹线型。进一步对产生不同线型的原因进行了分析计算,证明出现何种条纹与2个平面反射镜中虚光源的相对方位有关。Miehelson interferometers are usually used to observe the amplitude-splittine interference streaks. But the line-shapes of the streaks are seldom analyzed accurately. In this article we have developed the space curve equations of Michelson non localized interference streaks under the condition of point light source. Five kinds of line-shapes of interference streaks are acquired. They are circle, ellipse, parabola, hyperbola, and straight line. We further analyze the reasons of the different lines. The results show that the kind of interference streaks is determined by relative location of virtual light source in two mirrors.
