Abstract

In the transmitted light through scattering mammalian tissue, there should be a component that traveled along the optical axis of incident light beam. To detect this near-axis scattered component efficiently, we have introduced a time-resolved measurement technique to the previously developed spatially differential technique. With this technique, we can accurately determine the weighting coefficient for the differential process. In addition, we can estimate the increase of the path length in near-axis scattering. Through experimental study, the effectiveness of this technique to detect the near-axis scattered light was verified.
