<p><P>PROBLEM TO BE SOLVED: To provide a compact triaxial optical field sensor of high sensitivity capable of enhancing spatial resolution since a separation distance is narrowed between antennas. <P>SOLUTION: This triaxial optical field sensor has a structure of arranging on respective side faces of an equilateral triangle pole base block 5 a light modulator part 1 comprising a Mach-Zehnder interferometer for measuring orthogonal triaxial-directional electric fields, and a uniaxial optical field sensor comprising a metal antenna electrode 3 formed on a printed board, and is arranged in structure with a field detecting direction of the antenna tilted by about 54.7°with respect to a direction of a branched optical waveguide, and with the printed board 2 crossed three-dimensionally with the adjacent printed board 2 to detect the triaxial-directional electric fields orthogonal to each other. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
