Abstract

PURPOSE:To prevent the effect of vibration or temp. change, by fixing a Faraday effect material by an elastomer and fixing an optical head for transmitting and receiving light and a reflecting mirror for allowing light to reciprocate through the light path in the Faraday effect material to said Faraday effect material so as not to generate relative positional change. CONSTITUTION:A Faraday effect material 1 has light incident and emitting surfaces 2, 3 parallel to each other and a reflecting mirror 4 is provided in the vicinity of the light emitting surface and an optical head 13 having a polarizer 5, an analyzer 6, lenses 7, 8 and optical fiber end surface parts 9, 10 is provided in the vertical direction of the incident surface 2. A Faraday effect material 1 is fixed to the shield 16 arranged around a conductor 21 through a elastomer 17 to prevent the addition of stress due to vibration and temp. change. Then, the reflecting mirror 14 and the optical head 13 are strongly fixed to the shield 16 and a stand 14 to prevent relative positional change, and the shift of an optical axis and the effect of vibration or temp. change are prevented to measure a current with high accuracy.
