Electro-optical sensor for high intensity electric field measurement
| Abstract: The present invention is directed to an electro-optical sensor for high intensity electric field measurement. The electro-optical sensor was used to measure a strong 118 MV/m narrow pulse width (˜33 ns) electric field in the magnetically insulated transmission line (MITL) of a pulsed power accelerator. Accurately measuring these high fields using conventional pulsed power diagnostics is difficult due to the strength of interfering particles and fields. The electro-optical sensor uses a free space laser beam with a dielectric crystal sensor that is highly immune to electromagnetic interference and does not require an external calibration. |
