| 摘 要： | 高精度时间间隔测量技术对国民经济与国防建设意义重大，论述了一种新的高精度时间间隔测量方法，可以达到1ps量级甚至更高的测量精度。该方法利用声表面波色散延迟线作为时间内插器，时间内插器起到时间拉伸的作用，从而可以获得多个观测值，由于平均的效果，总的测量误差将被大大降低。理论分析与仿真实验均表明该方法可以达到很高的时间测量精度，是切实可行的。

| Abstract: | High-precision time interval measurement techniques play a significant role in the econo- my and the military. The paper deals with a novel high-precision time interval measurement method up to 1 ps or even higher precision. The method utilizes a surface acoustic wave dispersive delay line as a time interpolator. The time interpolator can have the form of a time stretcher, so as to get many observations. Thanks to possible averaging, the overall error can be greatly reduced. It＇ s indicated, by the theoretic a- nalysis and experiment, that the time interval measurement method is practical with high precision. |
