Abstract

Effective imaging in unknown volumetric scattering media presents significant challenges, particularly in fields such as underwater imaging and remote sensing. Here, we propose a practical method utilizing deconvolution with a photon round-trip propagator derived from the diffusion equation to image objects deeply submerged in turbid water. Using a single-photon camera and a low-power laser, we experimentally demonstrate depth tomography imaging of objects submerged in highly turbid water at 10 attenuation lengths without prior information. Our method is non-invasive and features self-extraction of parameters, offering practicality and broad applicability, with notable potential in underwater imaging and remote sensing.

使用光子往返传播器的扩散激光层析成像

在未知体积散射介质中进行有效成像是一项重大挑战，特别是在水下成像和遥感等领域。在这里，我们提出了一种实用的方法，利用反褶积和由扩散方程导出的光子往返传播子来成像深度淹没在浑浊水中的物体。使用单光子相机和低功率激光器，我们实验演示了淹没在高浑浊水中的物体在10个衰减长度下的深度层析成像，没有先验信息。该方法具有非侵入性和参数自提取的特点，实用性强，适用性广，在水下成像和遥感领域具有显著的应用潜力。

期刊介绍： Optics and Lasers in Engineering aims at providing an international forum for the interchange of information on the development of optical techniques and laser technology in engineering. Emphasis is placed on contributions targeted at the practical use of methods and devices, the development and enhancement of solutions and new theoretical concepts for experimental methods. Optics and Lasers in Engineering reflects the main areas in which optical methods are being used and developed for an engineering environment. Manuscripts should offer clear evidence of novelty and significance. Papers focusing on parameter optimization or computational issues are not suitable. Similarly, papers focussed on an application rather than the optical method fall outside the journal''s scope. The scope of the journal is defined to include the following: -Optical Metrology- Optical Methods for 3D visualization and virtual engineering- Optical Techniques for Microsystems- Imaging, Microscopy and Adaptive Optics- Computational Imaging- Laser methods in manufacturing- Integrated optical and photonic sensors- Optics and Photonics in Life Science- Hyperspectral and spectroscopic methods- Infrared and Terahertz techniques
