主要介绍和分析在浊度测量中为避免背景光的干扰,采用调制光强测量浊度的新方法,并介绍如何对从光 信号到电信号的非线性转换作线性化处理。最后,对测量过程在计算机上用MATLAB进行仿真。
This paper mainly introduces and analyzes a new method to measure turbidity by modulating the intensity of light in order to avoid interference of background light in the turbidity measurement and introduces how to linearize the nonlinear conversion from optical signal to electrical signal. Finally, the measurement process is simulated on the computer using MATLAB.
