脉冲电场测试中的激光供电技术
|
摘要
为解决脉冲电场测试系统中的供电问题,设计了一套激光光纤供电系统,该系统由激光器、多模光纤及光电池构成。重点研究了激光器与光纤的耦合问题,设计了透镜系统对激光器输出光束进行准直和压缩。通过MOCVD法研制了Ga As光电池,并制作了椭球形"光伏眼"来提高光电转换效率。仿真和实验表明:采用透镜耦合时,激光器与光纤的耦合效率可达80%以上,远远高于直接耦合时的16%,改进后的"光伏眼"耦合效率相比直接耦合时提高了54. 5%,激光供电系统的转化效率在40%以上。该系统的研制为解决脉冲电场的供电问题提供了一种方案。
E-field test is usually applied by one dimensional electric field sensor which is constituted of monopole antenna. For the directional character of the monopole antenna,the test result is always related to the location of the electric field sensor. In order to overcome this defect,a 3-D omnidirectional electric field sensor is designed. It is made up of monopole antenna and 3 mutually orthogonal pyramid used as reflective surface. The optimum design parameters of the 3-D pulse electric field sensor probe are determined according to the simulation of the electric field sensor on electric field under test and the influence of load impedance and the effect of antenna size characteristics of the test in the simulation software CST2012. Based on this,a 3-D pulse electric field sensor probe is made,and its major performance indicators are tested. The system provides a solution to solve the power supply problem of pulse electric field.
