The real time phase detector is constructed with a simple circuits. The amplitude and frequency of the vibrations are measured by synchronously detecting the phases in interference signal.
利用简单的电路构成实时相位检测器，对干涉信号中的相位信号进行同步检测，最终获得实际振动的振幅频率。
A phase detector is a device that takes two signals. If both have the same phase and frequency the output is zero.
鉴相器是一个有两个输入信号的器件，如果二者具有相同的相位和频率则输出为零。
