摘　　要：载波的相位对其参考相位的偏离值随调制信号的瞬时值成比例变化的调制方式,称为相位调制,或称调相。本文拟采用杨氏干涉装置,测量其相位调制特性。具体内容包括搭建杨氏干涉光路,完成数据的采集以及实现干涉条纹的处理,得到相位调制特性。The phase modulation or phase refers to a modulation way in which the carrier phase will proportionally change along with the instantaneous value of the modulated signal to the reference phase deviation value modulation. This paper plans to use Young＇s interference device to measure the phase modulation characteristic. The specific contents include building Young＇s interference light path,completing the data collection, and achieving the process of interference fringes, obtaining the phase modulation characteristics.
