摘要
以量子安全通信系统的硬件为实验平台,研制了动态偏振控制器(DPC)的驱动模块和性能监控系统。设计中,采用嵌入式ARM控制器通过自制的驱动模块驱动DPC,同时检测DPC的输出光强,将其随工作电压变化的曲线直观显示于终端计算机上,并测量出半波电压。实验结果与理论性分析验证了方案的可行性和可靠性。
The driving module and performance monitoring system for dynamic polarization controller（DPC） are designed and fabricated by employing the hardware of a quantum security communication system. The DPC is driven by the driving module through the control of ARM. Meanwhile,the output light intensity of DPC is detected and its curve according to the applied voltage is shown on the terminal computer screen by the specific software. The half-wave voltage can also be measured by analyzing the curve. The feasibility and reliability of the scheme are verified through the experimental result and theoretical analysis,
