摘　　要：介绍用光学传感方法对溶液浓度进行选择性测量.讨论了光与物质相互作用所产生的反常色散现象;分析了具有吸收谱的物质的复折射率与波长的关系;研究了反射率的衰减及衰减全反射现象.实验结果表明,这种传感方法对溶液浓度的选择性测量是有效的.This paper deals with the selective measurement of solution concentration by using optical sensitive method. The anomalous dispersion which originates from the interaction between light and matter is discussed. The relation of complex refractive index of matter having absorption band and wavelength is analyzed. The attenuation of reflectivity and attenuated total reflection are studied. Experimental results show that the sensing method is feasible to selective detection on concentration measurement.
