PHOTOELECTRIC MAGNETIC FIELD SENSOR AND PHOTOELECTRIC MAGNETIC FIELD DETECTION DEVICE

摘要

PROBLEM TO BE SOLVED: To separately but simultaneously acquire multipoint magnetic field information and multipoint electric field information. ;SOLUTION: A sensor body 12 comprises a piece of optical crystal 14 and a set of array lenses 16 formed by setting a plurality of lenses 16A in array or arranging them into a planar shape for respectively adjusting the diameters of light beams. The respective lenses 16A forming the array lenses 16 are bonded and fixed to the optical crystal 14, and the optical crystal 14 can be disposed in an electromagnetic field so that electric field information and magnetic field information can be detected by the optical crystal 14. A light source for generating arrayed laser beams L comprises a laser beam emitter, optical fiber, a lens array for collimation, and the like.;COPYRIGHT: (C)2004,JPO
