When the intensity of light reduces to single-photon level, the shot noise becomes dominant. Random scatter, especially the time-varying media will highly increase the photon-limited imaging challenge that the traditional imaging means are inadequate to cope with. In this paper, we develop a new scalable “one to all” imaging approach which focuses on dynamic scattering imaging under photon-limited condition. When the dynamic media optical density is five, we apply this principle to inverse scattering problem and retrieve high-quality images in a real-time way using as little as $\sim$0.4 valid detected photons per pixel on average successfully. The effects of lighting intensities and perturbations are analyzed to highlight special significance of the work. The ultimate results demonstrate that one trained strategy is robust to a wide range of statistical variations in dynamic media, which outperforms common “one to one” method and improves the practical utility efficaciously. This non-invasive imaging work promises a wide prospect in photon-limited scattering applications such as in vivo bioimaging and so on.

当光的强度降低到单光子水平时，散粒噪声将占主导地位。随机散射，尤其是随时间变化的介质，将极大地增加传统成像手段不足以解决的光子受限成像难题。在本文中，我们开发了一种新的可扩展的“全民”成像方法，该方法着重于光子受限条件下的动态散射成像。当动态介质的光密度为5时，我们将此原理应用于反散射问题，并使用最少的数据以实时方式检索高质量图像。$〜$平均每个像素成功检测到0.4个有效光子。分析了照明强度和扰动的影响，以突出工作的特殊意义。最终结果表明，一种经过训练的策略对于动态媒体中的各种统计变化均具有鲁棒性，其性能优于常见的“一对一”方法，并有效地提高了实用性。这项非侵入性成像工作有望在光子受限的散射应用（例如体内生物成像等）中具有广阔的前景。
