Abstract

A pulsed terahertz imaging system has been developed for potential use in vivo. Few data are available regarding the optical properties of human tissue at terahertz frequencies. This work demonstrates transmission measurements through human ex vivo tissue sections, and determines broadband refractive indices, and broadband and frequency dependent absorption coefficients. The data presented here are the first systematic measurements of this type. Significant differences were found between a numbers of human tissue types.
