Electric field measuring method and electric field measurement equipment

摘要

PURPOSE:To provide the method and device capable of directly measuring the electric field at an optional position. CONSTITUTION:An electric field measuring device is constituted of a laser beam generator 1, an image forming optical system 2 and a fluorescence detector 3. The measurement object apparatus M of the electric field is installed in a container C sealed with the gas X generating the Stark effect, and a power source V generating the electric field is connected. When a laser beam is transmitted from the laser beam generator 1 into the gas X in the electric field measuring device, the electric field generated around the measurement object apparatus M is applied to the laser beam, the energy level of the laser beam is changed by the applied electric field, the fluorescent spectrum with a specific wavelength is generated, and the fluorescent spectrum of the laser beam is changed. The change of the fluorescent spectrum is extracted from the side by the image forming optical system 2 in this device, it is measured by the fluorescence detector 3, thus the magnitude and distribution of the electric field are measured.
