Abstract

Phasic difference temperature error of quarter wave plate is one of the primary errors of fiber optic current transducer (FOCT). Polarization transform procedure of polarized light at quarter wave plate is analyzed. The influence principle of phase difference temperature stability to FOCT scale factor is disclosed. Afterwards, temperature error model of the plate is deduced. By introducing another A/D and performing unequal duty ratio square wave modulation, DC component and kurtosis information of the interference output are distilled respectively. Thus, a temperature error compensation scheme is designed with these two parameters. The experimental results show that FOCT scale factor error is decreased from ±0.75% to ±0.25% at -40-60°C by employing the compensation process.
