光声信号实时归一化系统的研究

A Study on The Real-time Ratio System of Photoacoustic Signal

本文基于光声信号和光电探测器的特性,提出了光声信号实时归一化方案,消除了光源波动引起的测量误差。

Based on the characteristics of photoacoustic signal and pho-todetectors,this paper presents the programme of real-time ratio to the phot-oacoustic signal.The measurement error by the fluctuation of the source int-ensity is eliminated.
