<p>An optical electric field sensor is constituted of optical parts (2-4 and 11-13) including an optical crystal and it is used to measure the intensity of a naturally or forcibly generated electric field by utilizing such a phenomenon that the intensity, phase, or polarization direction of light changes when the light is passed through the electric field. The optical parts are arranged and enclosed in a package (7) formed of at least one kind of material selected from such a glass material as quartz, ceramics, such a plastic material as antistatic vinyl chloride. When the main surface section of the package (7) is satinized, a greater effect can be obtained. The optical crystal having an electrooptic effect is enclosed in an heat-insulating material. In addition, a conductive resin is applied to the entire surface of the substrate of the optical crystal and a silicon resin is applied between modulating electrodes. <IMAGE></p> |
