摘要：
An optical depolarized structure of depolarized gyroscope is given. In this structure, polarization maintaining fiber (PMF) and loyt depolarizer are used in the output of light source. The polarization error of coherent light in the detector is calculated, and at the same time, the relationships of the four connecting angles-α, γ, μ θ to the polarization error and the optimum span are discussed. The parameters of fiber coin transfer matrix are evaluated into the formula of polarization error, and the error is 1.1 ×10-30/h.
