MICRO DIAMETER THREE-AXIS ELECTRIC FIELD SENSOR AND MANUFACTURING METHOD OF THE SAME

摘要

PROBLEM TO BE SOLVED: To solve a problem in which reduction in dimensions of an optical sensor is desired, but the reduction therein confronts pains-taking difficulty in terms of machining for allowing for exhibition of desired performance.;SOLUTION: The micro diameter three-axis electric field sensor contains: a detection element; two pieces of prisms; a wavelength plate; three pieces of optical fiber collimators; and a holding tool. The detection element is a hexahedron of an electro-optical effect crystal. Each of two pieces of prisms has one surface of each orthogonal surface optically bonded to an adjacent surface of the detection element. To one surface of the wavelength plate, an adjacent surface to the adjacent surfaces bonded to the prism of the detection element is optically bonded and other orthogonal surfaces of the prism are optically bonded, and to other surface of the wavelength plate, the holding tool holding the optical fiber collimators is optically bonded.;COPYRIGHT: (C)2014,JPO&INPIT
