我们提出了一种利用散射现象中的三维记忆效应通过散射介质进行无创三维成像的方法。在所提出的方法中，基于三维相位检索算法，通过轴向扫描图像传感器捕获的散斑图像的三维自相关来重建散射介质中的物体。我们通过在漫射器之间使用三维打印物体，通过无透镜设置实验演示了我们的方法。 (C) 2019 美国光学学会
We present a method for noninvasive three-dimensional imaging through scattering media by using a three-dimensional memory effect in scattering phenomena. In the proposed method, an object in a scattering medium is reconstructed from a three-dimensional autocorrelation of speckle images captured by axially scanning an image sensor, based on a three-dimensional phase retrieval algorithm. We experimentally demonstrated our method with a lensless setup by using a three-dimensionally printed object between diffusers. (C) 2019 Optical Society of America
