Abstract: A measurement technology of ellipsometry called graze was put forward. Electrochemical reactions of K 4 Fe(CN) 6 /K 3 Fe(CN) 6 on glass electrode deposited indium oxide were studied with both the graze ellipsometry and cycilic voltammetry. The results indicated that ellipsometric parameter and its change during the electrochemical reactions could be confirmed with graze ellipsometry, and the regularity was corresponding to the process of electrochemical reaction. So study for electrode system could be processed with the graze ellipsometry. The graze ellipsometry could also be applied to analyze properties of diffusion layer and prosthesis limitations of other technologies.
