ABSTRACT:
By using an electric field sensor comprising a sensor head 100 for producing a transmitted light wave having an intensity which varies in dependence upon an intensity of an electric field applied thereto, an optical fiber 8 for delivering a light wave from a light source 1 to the sensor head 100 to make the light wave be incident thereto, an optical fiber 9 for delivering the transmitted light wave of the sensor head 100 to a photoelectric transducer 10, and a measuring unit 11 for measurement and display of an electric signal from the photoelectric transducer 10, an electromagnetic noise or an electromagnetic leaking wave is detected as variation of the light intensity by locating the sensor head 100 in the vicinity of a source of the electromagnetic noise or the leaking wave without contacting the source.
