Laser light scattering in turbid media Part II: Spatial and temporal analysis of individual scattering orders via Monte Carlo simulation.

摘要: In Part I of this study [1], good agreement between experimental measurements and results from Monte Carlo simulations were obtained for the spatial intensity distribution a laser beam propagating within turbid environment. second part, validated model is used to investigate temporal effects distinct scattering orders on image formation. The contribution ballistic photons first twelve are analyzed individually by filtering appropriate data simulation results. Side-scattering forward-scattering detection geometries investigated compared. We demonstrate that positions final events independent particle concentration when considering given order in forward detection. From observation, it follows normalized each order, both space time, number density particles. As result, amount transmitted information constant directly related phase function association with acceptance angle. Finally, contrast analysis performed quantify at plane.
