Abstract

We compare the detected signal in the radiometric transillumination experiment for two sources: a gas laser with high coherence, and an LED with low coherence. Detected signal is significantly improved when a low-coherent light source is utilized, allowing us to clearly separate ballistic photons from those that undergo multiple scattering. The preliminary experimental results confirm the feasibility of the concept, requiring precise matching of the source coherence with the scattering behavior of the tissue (phantom) under study.
