Abstract
In this paper, self-mixing speckle generated in an erbium-doped fiber laser is numerically simulated and experimentally studied. The experimental model of self-mixing speckle based on an erbium-doped fiber ring (EDFR) laser is presented, and using the theories of light amplification and speckles, the model is theoretically analyzed. With the analytical results, the self-mixing speckle signal is obtained by numerical simulation. The signals represented different velocities are analyzed by fast Fourier transform (FFT), and the result shows that the mean speckle frequency of the signal and the velocity of a dynamic object are linearly related, which is agreed with that of the experimental study. The results of theoretical analysis and experimental study indicate that self-mixing speckle in an erbium-doped optical fiber laser can be used to the measurement of a dynamic object.
