混浊介质中的多次散射抑制了最佳光聚焦，从而限制了光学相干断层扫描（OCT）的穿透深度。然而，在混浊介质中的多重散射的影响，可以系统地控制通过成形的入射波前。利用麦克斯韦方程组的互易性和时域有限差分数值分析方法，研究了波前整形OCT在理想和实际结构下的极限性能，并与传统方法进行了比较。结果表明，根据OSA开放获取出版协议的条款，优化的撞击波前显著增强了OCT的穿透深度。（C）2018年美国光学学会
Multiple scattering in turbid media inhibits optimal light focusing and thus limits the penetration depth in optical coherence tomography (OCT). However, the effects of multiple scattering in a turbid medium can be systematically controlled by shaping the incident wavefront. The authors utilize the reciprocity of Maxwell's equations and finite-difference time-domain numerical analysis to investigate the ultimate performance bounds of wavefront shaping-OCT under ideal and realistic configurations and compare them with the conventional method. The results reveal that the optimized impinging wavefront significantly enhances the penetration depth of OCT.
