摘要
To image objects that are present in a random medium, one needs to know how sensitive measurements are to different kinds of objects and to the position of those objects. Within the diffusion theory we generalize expressions that describe the sensitivity to extra scattering and extra absorption. The sensitivity is influenced by the geometry and by the boundaries of the medium. We describe how sources and detectors at different boundaries have to be handled theoretically. We then compare an unbounded medium, a medium having a black boundary, and a medium having a mirror as a boundary and study the differences in sensitivity. Our results are confirmed by experiments.
