摘　　要：抗散射成像一直是光学成像领域的一个挑战性问题。数十年来,研究人员对此问题进行了广泛而深入的研究,并发展了多种方法和技术。文中综述了抗散射成像的基本原理、研究现状、不同方法的优势和局限性,以及潜在的发展方向。文中从计算光学的视角出发,对散射成像系统中各个模块的功能进行了分类,并将现有的抗散射成像技术分为六类进行详细介绍:弹道光提取技术、散斑相关成像、光子计数成像、散射补偿技术、计算光学成像技术和深度学习技术。其中,弹道光提取技术是最早的研究方向,随后对于光信息的利用逐渐深入,散斑相关成像,以及光子计数成像进入人们视野。而随着光学元件的发展,基于空间光调制器的散射补偿技术也引起了人们的关注。近年来,计算鬼成像技术因其独特的成像机制而成为新的研究焦点,并与深度学习技术一同推动了抗散射成像技术的进步。文中的内容旨在帮助研究人员理解各种抗散射成像技术的原理和最新进展,明确不同技术的特点和应用场景,以促进抗散射成像技术的进一步发展。Significance Anti-scattering imaging is always a challenging problem in the field of optical imaging.For decades,researchers have conducted extensive and in-depth research on this issue and developed a variety of methods and technologies.Scattering media are ubiquitous in the imaging process,which makes the application of scattering imaging technology very extensive.In the medical field,scattering imaging is used to reduce the influence of scattering characteristics of biological structures and tissues on medical image acquisition.In the field of ocean and water detection,scattering imaging is used to solve the problem of optical imaging quality degradation caused by a large number of scattering impurities in water.In the field of military and environmental observation,the elimination of scattering factors such as water mist and smoke in the environment is very important;even in the field of astronomy and remote sensing observation,how to detect the weak light signal scattered through the atmosphere to achieve imaging also belongs to the application of scattering imaging.It is not difficult to imagine that the development of scattering imaging technology will continue to promote progress in many fields.Progress First,starting from the basic principle of scattering,the physical process and key parameters of scattering are introduced,including the causes of scattering,photon characteristics,and the differences in scattering types caused by different particles.Because the light wave undergoes multiple scattering,the wavefront is distorted,and the light no longer propagates in a straight line,losing the target information originally carried by the light,which makes it extremely difficult to obtain effective target information or form a clear image.Therefore,the research of scattering imaging technology mainly focuses on how to recover the target in the scattering scene.This paper introduces the theoretical framework of computational optics to analyze the scattering imaging technology.
