摘　　要：The self-mixing fringes which shift due to every one-twentieth wavelength displacement of the target are observed. Taking advantage of the dual reflectors in the external cavity of lasers, the resolution of the sensors has been improved by 10 times. The role of the each reflector has been discussed in detail.The self-mixing fringes which shift due to every one-twentieth wavelength displacement of the target are observed.
