我们表明，由光学相干显微镜（低相干干涉）提供的多重散射拒绝可以是不完整的光学混浊介质和多重散射体现在两个不同的方式。多个小角度散射导致有效探测场比一阶光束消光模型预期的更强，但包含扭曲的波前，其相对于那些大于未散射入射光束的结构增强了小结构的表观反射率。多次广角散射产生宽漫射雾度，降低后续特征的对比度。
We show that the multiple-scatter rejection provided by optical coherence microscopy (low-coherence interferometry) can be incomplete in optically turbid media and that multiple scattering manifests itself in two distinct ways. Multiple small-angle scattering results in an effective probe field that is stronger than expected from a first-order beam extinction model, but that contains a distorted wave front that enhances the apparent reflectance of small structures relative to those that are larger than the unscattered incident beam. Multiple wide-angle scattering produces a broad diffuse haze that reduces the contrast of subsequent features.
