    Graphical Abstract
    • Abstract
  • A novel method for phase measurement is presented. In the method, the position of the bell-like optoelectronic pulse peak signal from a coordinator gyroscope was accurately measured, and the position was used as time reference to measure the phase. The time interval between two signals and their phase lead or lag was determined. Some measures were taken to overcome the disturbance in the ambient environment. The experiment proves that the method enables simple circuit as well as fast, accurate and reliable measurement.
