Abstract

Speckle correlation-based scattering imaging is an ingenious field, as it allows for the efficient reconstruction of object images using computational techniques in a simple setup. However, this method typically necessitates high-contrast speckle images captured in a darkroom environment, restricting its applicability to specific scenarios. Here, we present a fast and non-darkroom imaging framework, namely FNDI, for reconstructing objects through scattering media under ambient light interference. Specifically, a speckle illumination model is established guided by the total variational Retinex (TV-Retinex) theory, and the speckle illumination component is adjusted to obtain an enhanced speckle with significantly improved contrast. Then, a modified Fienup algorithm with the iteration-driven shrinkwrap (IDS) strategy is employed to rapidly reconstruct the object image through tens of iterations. Extensive experiments are conducted under different lighting conditions to evaluate FNDI in comparison with existing non-darkroom methods and the classical speckle correlation method. The results demonstrate that FNDI is effective and efficient, making it highly attractive for practical scattering imaging applications.

基于斑点相关散射成像的快速无暗室解决方案

基于斑点相关的散射成像是一个独创的领域，因为它可以在一个简单的设置中利用计算技术高效地重建物体图像。然而，这种方法通常需要在暗室环境中捕捉高对比度的斑点图像，这就限制了它在特定场景中的适用性。在此，我们提出一种快速、非暗室成像框架，即 FNDI，用于在环境光干扰下通过散射介质重建物体。具体来说，我们以总变异雷廷克斯（TV-Retinex）理论为指导，建立了一个斑点照明模型，并调整了斑点照明成分，以获得对比度显著提高的增强斑点。然后，采用改进的 Fienup 算法和迭代驱动收缩包（IDS）策略，通过数十次迭代快速重建物体图像。在不同的照明条件下进行了广泛的实验，对 FNDI 与现有的非暗室方法和经典斑点相关方法进行了比较评估。结果表明，FNDI 有效且高效，因此在实际散射成像应用中极具吸引力。

期刊介绍： Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
