体光源模拟标定法测O2(1Δ)绝对浓度
Absolute O2(a1? ) Concentration Measurement in Singlet Oxygen Generator by Using the Piston Source Method
-
摘要: O2(1Δ)绝对浓度的测量,一直是SOG和COIL研究中的重要参数之一。体光源模拟标定法测O2(1Δ)绝对浓度,是把发光气体以某一流速引入一已知体积的流动光池中,再通过具有低象差失真的光学系统,把该体光源成象在探测器的有效表面上。探测器和测量仪器组成的测量系统,要经过标准光源和电学标定。本方法可测出O2(1Δ绝对浓度和其分压,O2(1Δ)产率等参数。其中O2(1Δ)浓度测量结果的相对误差为20%。

Abstract: A calibrated piston source of light, which simulates a cylindrical-volume luminosity source, has been introduced to measure the absolute concentration of illuminant particles. It is proved that this Piston Source Method is one of the simplest and most convenient ways to measure the absolute concentration of illuminant particles, especially in real time measurements of O2(a1? ) in a singlet oxygen generator. The relative error of O2(a1? ) concentration is less than 20%.-
