Research on the performance evaluation system of fiber optic current sensor for microcurrent measurement

The current evaluation standard of fiber optic current sensor (FOCS) is messy and single, which cannot consider the accuracy and stability simultaneously. The analytic hierarchy process (AHP) method has been proposed to evaluate the comprehensive performance of FOCS. The complete evaluation system is designed, which lays a solid foundation for the scientific evaluation of FOCS，especially for microcurrent measurement.
