We report coherent imaging of objects behind opaque scattering media with only one piece of the power spectrum pattern. We solve the unique solution and improve algorithm speed for the inverse problem. Based on the proposed scattering-disturbance model, with only one piece of the Fourier transform power spectrum pattern under coherent illumination, we successfully reconstruct clear images of the objects fully hidden by an opaque diffuser. The experimental results demonstrate the feasibility of the reconstruction method and the scattering-disturbance model. Our method makes it possible to carry out snapshot coherent imaging of the objects obscured by scattering media, which extends the methodology of x-ray crystallography to visible-light scattering imaging for underwater and living biomedical imaging.
我们报告了仅使用一份功率谱图案对不透明散射介质后面的物体进行相干成像。我们解决了逆问题的唯一解并提高了算法速度。基于所提出的散射干扰模型，在相干照明下仅使用一份傅里叶变换功率谱图案，我们成功重建了被不透明漫射器完全隐藏的物体的清晰图像。实验结果证明了重建方法和散射干扰模型的可行性。我们的方法使得对被散射介质遮挡的物体进行快照相干成像成为可能，这将X射线晶体学方法扩展到用于水下和生物医学活体成像的可见光散射成像。
