Abstract

A method for the measurement of the absolute distance based on wavelength tuning technology of DBR fiber laser is presented. Experimental results show that the fringe number of the self-mixing signal and the target distance can reach a good linear relationship which agreed with the simulation results well. This paper demonstrate that DBR fiber laser present a powerful tool for the self-mixing technique and provide measurement of the distance up to 3.33 meters.
