The frequency linkage between the dual frequency combs was realized by using of the tracking feedback controlling circuit.The linkage characteristic was studied when the master frequency comb’s frquency is changed automatically and manully respectively. The results show that, the frequency of the slave frequency comb is varied following the automatic or manual frequency scanning of the master frequency comb. The max correlation coifficient between the frequency of the dual frequency combs is up to 0.99, which demonstrates the better linkage characteristic. Finally, the linked dual frequency combs was used in the abosulate distance measurement. The measured distance is 1.332 m, the interval is 0.2 s, the standard deviation of the experimental results is 0.35 μm with 16 times, and the measurement precision is less than 1 μm.
