Abstract

In this paper, we propose a partially reflecting boundary method for diffusive optical imaging of shallow targets in turbid media. An appropriate range of the effective reflection coefficient R_eff has been suggested between 0.0 and 0.7, in which the extrapolated boundary condition can be used to simplify the forward model. For a shallow target of approximately 0.5 cm deep from the surface, experimental data acquired with a reflecting boundary of R_eff ≈ 0.6 lead to significant improvement in the image quality compared with that from an absorbing boundary of R_eff ≈ 0.
