摘要: An electric current detector has a light source for generating having substantially linear polarization and predetermined direction, material transparent to the light, at least one characteristic exhibiting Faraday effect in response magnetic field generated by current. Also is launched into material, angle established between direction chosen permit separation of rotation from effects on birefringence material. A value 22.5° magnitude permits due
