摘要
设计了一个PC机与单片机联合工作以控制光幅度调制的自动控制系统,对系统结构、原理等进行了分析。本系统硬件由两大模块组成:光路模块和电路模块。光路模块的功能是实现电光信号的转换和检测。电路模块则用于对光路模块偏置电压偏移进行测控调整,使幅度调制稳定,也是光外调制器的核心设计模块。
This paper designs that PC and MCU work together to control an automatic control system of spatial light modulator. And this paper also briefly analyses the structure of a system, theory as well as the achievement.The hardware of this system consists of two modules： optcial circuit module and electrocircuit module. The function of optical circuit modules is to realise the conversioh and detection of light signal. The electrocircuit module is used in commanding and adjusting the excursion of offset voltage on optical circuit module, and it also realises the stabilization of AM（Amplitude Modulation）. Especially, the electrocircuit module is the key of this paper.
