摘要: An electric reference signal channel is added to the main in a hybrid optical current sensor or voltage sensor. This has frequency that outside signal's band. A summing integrator of amplifier combines with signal, and combined signals drives an electro-optic device. device input CW signal. receiver converts received into Two band pass filters separate their respective paths. processing unit calculates ratio Therefore, drifts source all path are factored out.
