摘　　要：本文是对迈克尔逊干涉仪应用的拓展,利用迈克尔逊干涉仪测量运动物体的速度。以运动的物体替代迈克尔逊干涉仪的一反射镜,形成动态的干涉条纹,用光电二极管探测变化的条纹强度,得到随时间变化的电信号,用示波器记录,采用傅立叶变换方法处理实验信号,计算多普勒频移,测出物体的运动速度。实验表明测得结果误差范围在2%内。This article is the extending of the Michael interferometer application, the velocity of movement object is tested by the Michael interferometer. One reflector is substituted by a movement object ,then the dynamic interference image will be get ,the intensity of the image is detected by a photoelectricity diode, then we can get the dynamic electricity signal, the signal is memorized by an oscillograph, making the FFT translation to the signal, we can get the chang of the frequency, then the velocity will be solved. The error of the experiment result can＇ t exceed two percent.
