摘要
设计了一种激光测振仪，它实际上是一个迈克耳逊干涉仪，计算了用此仪器测得的信号的频谱，计算结果表明可以从频谱推算出振动的频率和振幅．所以在测量机械振动的其他方法不适用的情况下，这可能成为一种有用的新方法．
A laser Michelson interferometer is designed for measuring mechanical vibration. The spectrum of the signal measured by using the interferometer is calculated. The results of the calculation show that the frequency and the amplitude of vibration can be deduced from the spectrum. Therefore, this may be a useful newmethod in the case that other methods are not suited to measuring mechanical vibration.
