Abstract
To meet the requirements of MV/m intensity pulse electric field measurement,a single optical path type small volume broadband pulse electric field measurement system based on integrated optics is designed and developed.Based on electro-optical effect and electro-optic modulation principle,the amplitude and frequency response transfer function of the measuring system is established,the reception characteristics of the integrated optical probe are analyzed,the relationship between its sensitivity and bandwidth with the length of the waveguide is derived.The pure optical non-metallic single-optical waveguide structure is designed,and a method of adjusting the measurement sensitivity using crystal width is proposed,which raised the designed half-wave electric field more than 3 times.The passive probe size is less than 20 mm×10 mm×5 mm,the theoretical bandwidth is more than 4 GHz,and the maximum measurement range is more than 1.2 MV/m.The developed measurement system has applications in the fields of high-altitude electromagnetic pulse(HEMP),lightning(LEMP)and pulsed power technology.关键词
