| 摘 要： | 本文介绍测量物体振动的一种新方法。该方法由相干光源照明相位板,在空间产生恒定干涉场,将振动物体置于干涉场中,记录下带有物体振动信息的干涉条纹。根据此干涉条纹可定量分析物体振动的振幅。理论分析与实验结果相符。

| Abstract: | The present article introduces a new technique of measuring the vibration of objects. A laser is employed to illuminate the phase plate to produce a permanent optical interference field, The object is put in the interference field and the vibration information of the pattern is recorded, The amplitude of vibration is analysed by means of the interference pattern, This theory is fully verified by the result of experiments. |
