Reliability Evaluation Methods of Accelerated Degradation Test for Fiber-Optic Gyroscope Under Temperature Environment

Abstract Fiber Optic Gyroscope (FOG) is a kind of rotation sensor with high reliability and long lifetime. Accelerated life test hard to obtain enough failure data for evaluation. By analyzing mechanism, the sensitive environment stress performance degradation parameters FOG are determined. Then an accelerated (ADT) undertaken information. Wiener process introduced describe path Arrhenius model selected as model. Considering epistemic uncertainty in monitoring, interval linear regression ADT introduced. at operating evaluated. discussing assessment results, methods this paper feasible FOG.
