为了评价飞秒激光测距光源的稳定性，采用高速频率计对飞秒激光测距系统激光源的重复频率进行数据采集，通过LabVIEW编程计算艾伦方差，分析得出相位噪声与随机游走噪声对激光器重复频率稳定性的影响最为明显．
為瞭評價飛秒激光測距光源的穩定性，採用高速頻率計對飛秒激光測距繫統激光源的重複頻率進行數據採集，通過LabVIEW編程計算艾倫方差，分析得齣相位譟聲與隨機遊走譟聲對激光器重複頻率穩定性的影響最為明顯．

In order to evaluate the light source stability of femtosecond lasers distance measurement, the system collects the repeat frequency data of the light source using frequency meter, Allan Variance is calculated through LabVIEW program. The analysis shows that the key factors to the laser repetition frequency stability is phase modulation and random walk frequency modulation.
