Sensitivity of Boundary Walls in Photon Migration and Optical Imaging

Abstract

Time-resolved light scattering measurements around a cell containing intrahpid suspension were performed with transparent, absorbing, reflecting and water boundaries. In case of the reflecting boundary walls the collection of early light as well as diffuse signal was highly enhanced. When an absorber was introduced into the scattering medium the relative change in intensity profiles was found to be maximum for the reflecting walls suggesting that such a choice of boundary may be used to improve time-resolved shadowgrams as well inverse image reconstruction.
