Circuit Design of Weak Photoelectric Signal Detection
摘要
Abstract
The performance of photoelectric signal detection and acquisition circuit is directly connected to the accuracy and precision of the dust concentration measurement system.On the basis of analyzing the basic principles of the photoelec-tric detector and weak signal detection factors on the characteristics of the optical signal dust con-centration measurement system,by using differen-tial measurement structure,improving the stability of power supply photoelectric detector,choosing low noise,fast response and other measures of operational amplifier, a low noise, faster re-sponse,easy and practical weak optical signal de-tection circuit is designed,and successfully applied to the dust concentration measurement system.关键词
