Abstract :
In this paper, self-mixing interference measurement based on phase modulation is demonstrated using a fiber laser system. The measurement setup is built by an erbium-doped fiber laser and an integrated-optic phase modulator. Theoretical analysis, simulation results and error evaluation are presented. The system is experimentally applied to reconstruct the motion of a high-precision commercial PZT and a displacement measurement accuracy of λ/13 is obtained.
