在本文中，利用多重散射介质的自然随机化处理压缩成像问题。为了以这种方式利用介质，必须估计其对应的传输矩阵。为了进行校准，我们使用数字微镜器件(DMD)作为简单、廉价和高分辨率的二进制强度调制器。我们提出了一种相位恢复算法，该算法很好地适应于摄像机上的仅强度测量和输入的二值强度模式，既可以估计复杂的传输矩阵，也可以重建图像。我们以手写数字的MNIST数据集为例，展示了所提出的双相位检索算法的良好实验结果。
In this paper, the problem of compressive imaging is addressed using natural randomization by means of a multiply scattering medium. To utilize the medium in this way, its corresponding transmission matrix must be estimated. For calibration purposes, we use a digital micromirror device (DMD) as a simple, cheap, and high-resolution binary intensity modulator. We propose a phase retrieval algorithm which is well adapted to intensity-only measurements on the camera, and to the input binary intensity patterns, both to estimate the complex transmission matrix as well as image reconstruction. We demonstrate promising experimental results for the proposed double phase retrieval algorithm using the MNIST dataset of handwritten digits as example images.
