通过散射介质成像一直是现代光学成像领域的主要挑战。最近，已经报道了基于波前成形的通过散射介质的成像。然而，它还没有明确的研究应用基于光学记忆效应的迭代波前成形技术在通过散射介质的运动目标的速度估计。本文提出将联合收割机迭代波前整形技术与激光散斑对比度分析方法相结合，检测运动物体通过散射介质时的相对速度变化。进行了体模实验，以验证我们的方法。
Imaging through a scattering medium has been a main challenge in modern optical imaging field. Recently, imaging through scattering medium based on wavefront shaping has been reported. However, it has not been clearly investigated to apply the optical memory effect based iterative wavefront shaping technique in speed estimation of a moving object through scattering medium. Here, we proposed to combine the iterative wavefront shaping technique with laser speckle contrast analysis method to detect the relative speed changes of moving objects through scattering medium. Phantom experiments were performed to validate our method.
