| Abstract: | A novel method which can measure the phase measurement is presented, It measures accurately the peak value of the bell-like optoelectronic pulse signal from coordinator gyro rotor, which is used for the lime standard in phase measure mere. This system judges the phase difference and distinguish phase leading or lagging of two signals. Some practical methods are introduced to solve the problem caused by disturbing factors. The circuit based on this method is simple. This method is able to achieve high-speed, reliable and high-precision in practice. |
