| 摘 要： | 时域平均法是从混有噪声的信号中提取周期性分量的最有效方法.本文分析了时域平均法对光电信号进行滤波处理在激光绝对法校准振动传感器相频特性中的应用.通过对其原理的分析,证明了该方法在实现对有用信号滤波的同时也保证了信号的线性相位变化.

| Abstract: | The time domain average method is an efficient method to extract period componen ts from the signal mixed with noise. In this paper, the time domain average meth od is used to extract the interfere signal in calibrating the phase character of vibration sensor by laser interferometer. After analysed the principle of time domain average method, the conclusion can be got that this method can extract th e useful signal and keep the linearity phase change. |
