Demodulation errors ef fects on f iber-optic current sensor
Abstract
Harmonic imbalance and phase deviation affect the linearity and sensitivity of fiber-optic current sensor (FOCS). The effects of these two factors are theoretically analyzed. Both the harmonic imbalance and phase deviation must be restricted within a tolerable range of variation. By experimentally optimizing these two factors, the scale factor (SF) error of the current sensor within the range of 0.5% is demonstrated and implemented.
