摘要
本文介绍了研制GaAs:Cr,InP:Fe光导开关的过程,实验显示了开关对光的响应特性,利用光导开关来探测皮秒光脉冲的波形,并且利用光导开关的原理研制成新型的超宽带雷达实验室模型,实验显示了它的脉冲辐射和接收波形。
The picosecond photoconductive switches are developed and used to detect the pulse laser waveform. By using the photoconductive switches, a novel lab model of an ultrawide band (UWB) radar is also developed. The experimental results are given to show the performances of the swithches and the UWB radar.
