On designing of an Automatic Controlling Circuit for Stable Laser Frequency based on AD Sampling

AD(Analog-to-Digital)采样及其数据传输是从传感器和其它待测设备等模拟量转换为数字量并自动采集信息输送给其他设备的不可缺少的部分,并且通过计算机控制,可实现对参量的实时检测、显示与控制。随着信息技术的飞速发展,采用AD采样并通过数字传输的计算机自动控制方面的应用越来越广泛,如激光雷达的发射激光波长自动检测。本文给出了一种基于AD采样的激光稳频自动控制电路的设计,可有效实现对激光器发射波长的长期稳定的自动控制。

AD Sampling and its data transmission is the crucial part for converting analog signals in sensors to digital signals and transmitting the information signals to other equipment,and the detecting,displaying and controlling of parameters can be realized through computer controlling.With the rapid development of IT technology,the application of AD Sampling and automatic computer controlling through digital transmission have been widely used.This essay puts forward the designing of an automatic controlling circuit for stable laser frequency based on AD sampling,so as to effectively control the emission wavelength of laser in a long run.
