▎ 摘　　要

NOVELTY - The method involves adhering a two-dimension structure of graphene to a prism having different absorption of S-polarized and P-polarized lights. Refractive index of a substrate material is measured according to graphene polarization effect in real time by measuring difference of the polarized lights. The graphene is adhered to a transparent sheet. The prism is combined with an upper flange. A convex lens is utilized for focusing an incident light. USE - Method for measuring refractive index of a substrate material based on graphene polarization absorption effect for biological and chemical fields. ADVANTAGE - The method enables monitoring refractive index of the substrate material in real-time without a motor when refractive index s-polarized and p-polarized electric signal difference is changed. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a real time graphene polarization absorption effect measuring refractive index measuring device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic illustration of a real time graphene polarization absorption effect measuring refractive index measuring method.'(Drawing includes non-English language text)'
