Abstract

In this paper, an optical method for precisely estimating constituents of optical isomers (OIs) in mixed solution is presented. We convert the composition ratio of OI into polarization-rotation-dependent spin Hall effect of light (SHEL). The theoretical model between the SHEL and OI composition ratio is established in the geometrical-optics picture, and the spatial shift can be measured through weak measurement technique. Based on our theory, the concentrations of glucose and fructose in a mixed solution are separately obtained. Our accurate measurements of the chiral enantiomer composition can provide an avenue for chiral drug synthesis and analysis.
