摘要： An electric field sensor comprising a sensor head (100) that varies the intensity of light transmitted therethrough depending upon the strength of the applied electric field; an optical fiber (8) which leads light from a light source (1) to the head (100); an optical fiber (9) which leads the light transmitted through the head (100) to a photoelectric converter (10); and a measuring instrument (11) which measures and displays electric signals from the converter (10). This sensor detects electromagnetic noise or electromagnetic leakage through changes in intensity of light without bringing the head (100) into contact with a source of electromagnetic noise or leakage, but by positioning the head (10) near the source.

摘要： An electric field sensor comprising an input optical, an incoming waveguide (5) formed on a substrate (4), two branched waveguides (6) branched from the waveguide (5) on the substrate (4) and having refractive indexes variable depending upon the intensity of the applied electric field; an output wave guide (7) joined with the waveguides (6) on the substrate (4); and a shield member (8) provided near the guides (6) to shield part of the waveguide (6) from electric fields. A reflecting mirror (16) may be formed on the substrate (4) so as to reflect light from the guides (6). The substrate (4) may be formed of a ferroelectric substance, in which the respective regions of the two waveguides (6) are polarized in opposite directions.
