大气湍流对光学成像、遥感和自由空间光通信等应用构成根本性限制。近年来,自适应光学、波前调控及机器学习的进展,推动了湍流畸变抑制技术的发展。主动卷积照明(ACI)作为一种物理驱动的结构光传输方法,在极端湍流条件下表现出低畸变潜力。尽管其原理独特,但与其它物理驱动方法有概念相似性,可与数据驱动的深度学习模型互补融合。本文提出将ACI与基于神经网络的方法结合的框架,分析了学习表征如何支持ACI的关联注入机制。以卷积神经网络(CNN)和迁移学习为例,展示了该方法在湍流环境中的可行性,为未来ACI-深度学习混合架构提供了早期基础,推进了两类技术间的协同探索。
原文摘要 · Abstract (English)
Atmospheric turbulence imposes a fundamental limitation across a broad range of applications, including optical imaging, remote sensing, and free-space optical communication. Recent advances in adaptive optics, wavefront shaping, and machine learning, driven by synergistic progress in fundamental theories, optoelectronic hardware, and computational algorithms, have demonstrated substantial potential in mitigating turbulence-induced distortions. Recently, active convolved illumination (ACI) was proposed as a versatile and physics-driven technique for transmitting structured light beams with minimal distortion through highly challenging turbulent regimes. While distinct in its formulation, ACI shares conceptual similarities with other physics-driven distortion correction approaches and stands to benefit from complementary integration with data-driven deep learning (DL) models. Inspired by recent work coupling deep learning with traditional turbulence mitigation strategies, the present work investigates the feasibility of integrating ACI with neural network-based methods. We outline a conceptual framework for coupling ACI with data-driven models and identify conditions under which learned representations can meaningfully support ACI's correlation-injection mechanism. As a representative example, we employ a convolutional neural network (CNN) together with a transfer-learning approach to examine how a learned model may operate in tandem with ACI. This exploratory study demonstrates feasible implementation pathways and establishes an early foundation for assessing the potential of future ACI-DL hybrid architectures, representing a step toward evaluating broader synergistic interactions between ACI and modern DL models.
