Paper Abstract

A method using a pair of femtosecond frequency combs can realize ranging at a high precision of 1μm by Fourier Processing. In simulation of this system based on Matlab/Simulink, it is found that the choosing of repeating frequencies has great impact on frequency of the sampled signals, which influences the ranging precision a lot. The sampled signals are analyzed and classified into three types, which can be judgment criteria in system setting. Filter at Nyquist frequency is advised to decrease the edge effect of FFT, and a supplement means of cutting in data processing is proposed to improve precision.
