摘要：
We report a new configuration of the fiber optic voltage sensor based on the Bi12TiO20 crystal, which allows simultaneous measurements of both voltage and temperature. In our scheme, a quarter-wave plate, being an inherent element of voltage sensor, serves simultaneously as a phase-shifting element and as a temperature sensitive element. The sensor operates at two wavelengths (633 run and 976 run). The sensor has a linear temperature characteristic within the range of 10divided by70degreesh, providing the accuracy of temperature measurements of 0.3degreesh. As a voltage sensor, this device has a linear amplitude characteristic up to 1000 V-rms and the excellent temperature stability of 0.1% within the temperature range of 10divided by70degreesh.
