要約(英語): Highly sensitive potential difference sensor is developed with BGO Pockels sensor in longitudinal modulation geometry. By introducing multiple reflection method, the half wave voltage, which corresponds to the indicator of the sensitivity, is improved around 30 times, and the detectable potential difference with this sensor reaches less than 10V. The potential difference around 100V insulated wire is successfully measured with this sensor.
