ABSTRACT:
Drift compensation for the output signal of a magneto-optic current measuring system is achieved through the use of two light emitting sources, each at different frequencies, to generate two alternating optical input signals to the current sensor to establish a signal reference in order to compensate for signal drift caused by variable attenuator characteristics of the optical elements in the system.
