摘要
针对光学相控阵的结构特点和电控制方式,采用数模转换的原理,重点研究了以CPLD为核心的电控制系统,实现与计算机的串口通信,可独立控制多路串行数模转换模块,输出精确的模拟电压,达到可在线调试电压和控制光束快速扫描的目的。
The Electrical control system is very important for the optical phased array. Based on the method of digital to analog conversion and serial communication, the control circuit of the optical phased array uses CPLD as the main control unit. The Multi-channel serial digital to analog converter module can be controlled independently and outputs accurate analog voltages.
