Research of automatic gain control technology based on photomultipliers
为了压缩水下无线光通信系统中接收光信号的动态范围、提高有效通信距离，从自动增益控制技术的基础理论入手，利用光电倍增管增益可随工作电压改变的特性，设计出基于光电倍增管实现的自动增益控制电路，其数字控制部分以单片机为核心，并在空气中模拟水下实验。结果表明，该电路可以对接收光信号实现40dB的压缩，提高了水下无线光通信的有效范围。
In order to compress the dynamic range of the received optical signal in an underwater optical wireless communication system and increase the effective distance of communication , automatic gain control circuit based on variable gain photomultipliers was designed from the basic theory of automatic gain control technology .Single chip microcomputer was the core of the digital control part .The underwater experiment was imitated in the air .The results show th…查看全部>>
