20120121217 | PROBE FOR ELECTRIC/MAGNETIC FIELD - In an electric/magnetic field probe using an optical fiber, when a stress is applied to the fiber, the polarization state of the light propagating in the fiber changes, and the signal level of the electric or magnetic field detection becomes unstable. For coping with this problem, for suppressing the curve or waggle of the optical fiber caused by a stress applied to the fiber, an electric/magnetic field sensor unit composed of the fiber and EO/MO material is fixed on a quartz substrate, for example, and the part of the fiber other than the sensor unit is stored in an acrylic tube and fixed. Further, polarization adjustment parts like a polarization controller, an optical analyzer or the like is installed in the housing, so that a stress caused by wind pressure or contact is not applied to the fiber connected to the parts. | 05-17-2012 |
