Multiple scattering in optical coherence microscopy

摘要: We show that the multiple-scatter rejection provided by optical coherence microscopy (low-coherence interferometry) can be incomplete in optically turbid media and multiple scattering manifests itself two distinct ways. Multiple small-angle results an effective probe field is stronger than expected from a first-order beam extinction model, but contains distorted wave front enhances apparent reflectance of small structures relative to those are larger unscattered incident beam. wide-angle produces broad diffuse haze reduces contrast subsequent features.
