ANOMALOUS DISPERSION OF MATTER USED TO REALIZE THE SELECTIVE DETECTION IN DENSITY
利用物质反常色散实现浓度选择性测量

A new sensing method was presented, which is advantageous for selective detection of liquid density. The anomalous dispersion which is the theoretical basis of the new sensing method was discussed. The dependence of complex refractive index of matter having absorption band on wavelength was analyzed. The attenuation of reflectivity and the attenuated total reflection were studied. Initial experiments show that the sensing method is feasible.
