In this paper we analyze the frequencycorrection caused by a finite beam width in an optical gyro.
本文分析了光陀螺中由于有限光束宽度对拍频频率的修正因子。

One method is phase difference correction of partly FFT; the other is FFT frequencycorrection with quadratic interpolation.
一是利用分段FFT的相位差修正算法，二是基于二次内插的频率FF T校正法。

It adopts auto adaptive step to track the frequency offset, so that it can shorten the AFC (Automatic frequencycorrection) tracking period and improve frequency precision.
