Paper Abstract

The measurements of refractive index and thickness of various transparent plates and films are very important for quality control. Additionally, the knowledge of refractive index, and thickness is significant in biomedicine for the treatment of many kinds of tumors. In this paper, we propose a new method for noninvasive and simultaneous measurement of refractive indices and physical thickness of specimens, which consist of surrounding and interior components with different refractive indices. In our experiment, we measure the refractive index and the physical thickness of a multimode fiber and a lotus root with a hollow hole, respectively. The experimental results verify the feasibility of this method.
