摘要：
Speckle is one of the main obstacles to application of self-mixing interferometer. Self-mixing model reflecting speckle is of great theoretical and practical significance in self-mixing interferometry. In the paper, we suggested an improved model which can clearly explain the effect of speckle on self-mixing signal, and draw some important results such as a mechanism of feedback coefficient intensity variation induced by speckle and effects of the surface orientation on the signal. The proposed model and method will provide an effective tool for practical application of self-mixing interferometer.
