摘要
介绍了一种以内调制光电探测器为传感器的高精度微弱激光检测系统,并针对光电探测器输出信号较弱且动态范围宽的特点,提出了一种新型可编程自动增益放大器的设计方法。介绍了该方法的硬件原理和软件设计。
A high-precise detecting system for low laser has been introduced. The sensor is a photodetector. Aiming at the faintness and variety of output signals of photodetectors, the design method of a novel programmable automatic gain amplifier is advanced. The hardware principle and software design of this method are introduced.
