摘　　要：光纤传感在线检测系统是一套能对染液浓度进行在线检测的新型装置,光纤传感在线检测系统染液浓度和吸光度的线性相关性以及其测试结果与分光光度计的测试结果是否吻合关系到光纤传感检测系统的稳定性。结果表明,使用光纤传感在线检测系统测试时,染液浓度和吸光度的线性关系良好,线性相关性均在0.99以上;光纤传感在线检测系统与723型可见分光光度计的测试结果也几乎完全相同,相对误差均不超过0.1%。Optic fiber sensing on line system is a new apparatus applied in testing dyes concentration in real time. It is important to investigate the linear correlation between dyes concentration and absorbance. And the stable testing system can provide coincident testing results with that of spectrophotometer. The results showed that, dyes concentration tested by optical fiber sensing on line system had excellent linear correlation with absorbance which is above 0.99. The relative error of the result tested by the new apparatus and 723-spectrophotometer is not more than 0.1%.
