This principle can ...
Web1. Introduction. The refractive index (RI) of biological tissue is a basic material parameter that characterizes how light interacts with tissue. 1 In many optical studies, a rough estimate of RI of the tissue under study, based on the fact that the main constituent of tissue is salt water-filled cells or more precisely a mixture of salt water and proteins, is often used. 2, 3 …
