Laser Frequency Modulated Ranging Method Based on Triggering Resample from Outside Clock Signal
We propose a triggering resample method by improving frequency modulated continuous wave laser ranging technology. In our method, the auxiliary signal triggers the data acquisition card to sample both of the measurement signal and the auxiliary signal, and then, the extreme points of the acquired auxiliary signal are used to re-sample the measurement signal. The experimental results show that the minimum standard deviation of the proposed triggering resample method can reach 12 μm.
