Abstract
In this paper, an integrated optical sensing system qualified to measure DC E-field in industrial scene is proposed. The key components of the sensing system consist of a probe and a rotating arm. The probe rotates back and forth driven by the arm, so that the imposed DC E-field is converted to AC E-field. The output signal of the measuring system is approximately a sinusoidal type, with the peak-to-peak value in proportion to the applied DC E-field strength. Experimental results showed the detectable E-field range was from 20 V/m to 60000 V/m.
