A reliability assessment method of Fiber Optic Gyro
Erbium-doped fiber source for Fiber Optic Gyro (FOG) uses doped fiber to produce super fluorescence with laser pumping.It has higher output power,wide spectral lines,lower temporal coherence,good temperature stability and long life,which are perfect source for high precision FOG.To solve the problem of reliability analysis of erbium-doped fiber source for FOG with zero failure data,Weibull distribution is chosen as the life distribution model of erbium-doped fiber source on basis of the failure mechanism analysis in this paper.And Bayesian theory is used to estimate the failure rate in different time with zero failure data,then the parameters of the life model are estimated to get reliability index of erbium-doped fiber source.The method greatly decreases the number of test samples because of Bayesian estimation has take advantage of experience information,and also,it overcomes the shortcoming of relying on failure data when using traditional reliability assessment methods.So it has great value on project application.
