浴帘效应的模型发展及应用扩展(特邀)

Model development and applications extension of the shower-curtain effect (invited

  • 摘要: 散斑(自)相关和波前调制等成像技术是克服非均匀介质散射影响的高效并重要的光学成像手段。而该类技术依赖于光学记忆效应,因此视场有限且动态介质会退化其成像质量。浴帘效应是一种常见且不受散射介质动态变化和视场限制的效应。近年来,随着多种计算成像技术的发展,浴帘效应也被融合到其他克服散射的成像恢复技术中并应用于不同散射成像场合,已经展现出相较传统散射成像技术的独特优势。文中概括浴帘效应的物理模型演变,从调制传递函数出发,综述光学厚度、孔径大小等因素对浴帘效应的影响,介绍浴帘效应和傅里叶域浴帘效应在散射成像领域的应用。讨论傅里叶域浴帘效应与其他基于相位迭代算法成像技术的区别与联系,展望其与其他计算成像技术结合的可能。

     

    Abstract: Imaging techniques such as speckle correlation and wavefront modulation are efficient and important to overcome the scattering effect caused by inhomogeneous media. However, the field of view of these techniques is limited, and the dynamic scattering media degrades the image quality due to the dependence on the memory effect. The shower-curtain effect is a common effect that is not limited by the field of view and the dynamic scattering medium. In recent years, with the development of various computational imaging techniques, the shower-curtain effect has been applied to different scattering scenes to overcome the scattering effect, combined with other imaging recovery methods, and has shown some unique advantages compared with traditional scattering imaging techniques. This paper summarizes the evolution of the physical model of the shower-curtain effect based on the modulation transfer function, analysing the influence of optical depth and aperture sizes. The applications of the shower-curtain effect and the Fourier domain shower-curtain effect in the field of scattering imaging are depicted. The difference and relationship between the Fourier domain shower curtain effect and other imaging techniques based on a phase iterative algorithm are discussed, and the possibility of combination with other computational imaging techniques is proposed.
