一种新型高精度频标比对系统

A Novel High Precision Frequency Comparison System

基于对李沙育图进行图像处理的思想,从等效鉴相频率的原理出发,提出了一种新型的高精度频标比对系统。该系统可以捕捉图像翻转周期非常短的李沙育图,通过图像处理可以比对频差比较大的信号。并且构成该系统的设备简单,精度却可以大大提高。

A new high precision frequency comparison system based on the idea of the Lisaajous curve processing and the concept of the equivalent phase comparison frequency is introduced in this paper. Lissajous curve with short image cycle periods can be caught and signals with large frequency difference can be compared by this system. The system can be built up by some simple devices,but the measurement precision can be improved significantly.
