Abstract: | Nonreciprocal errors in fiber-optic current sensors, which are induced by environment fluctuations such as temperature and linear and angular vibrations, are specified. These errors in three current sensor configurations are evaluated and compared theoretically. The comparison indicates that the in-line sensor with strip waveguide modulator has the best resistance to the mentioned three environment fluctuations. Methods that may be used to suppress the nonreciprocal errors in different sensor configurations are suggested. |
