自己結合効果型レーザセンサを用いた振動計測における統計的特徴を利用した信号処理方法

抄録

In this paper signal processing using statistical algorithm for vibration measurement is reported. The algorithm uses a statistical feature of standard deviation for sinusoidal vibration and enables higher accuracy than Peak-to-Peak method. Additionally the algorithm achieves accuracy as well or better, with less hardware compared with the FFT method. This method gave good results in simulations and actual measurement values. The method is widely applied for a self-coupling effect sensor and other vibration sensors.
