electromagnetic field measurement system the electric field sensor, magnetic field sensor, electromagnetic field sensor, and using them

摘要

Magnetic field sensor or electric field sensor comprises an optical fiber (112), and a magnetic optical layer electro-optical layer or (115). Magneto-optical layer is provided end face at the end of the optical fiber (112) to (135) on the electro-optical layer or (115). End face of the optical fiber (112) (135) is a convex surface. The optical fiber is a substantially conical end portion is stretched, magneto-optical layer or electro-optical layer may be provided on the side of the tip of the substantially conical. It may further comprise a dielectric layer between the end face and the magneto-optical layer or electro-optical layer.
