散射在光的成像过程中无法避免,传统的光学成像技术很难解决散射引起的光波前畸变及图像失真等问题。近年来,大量的研究成果表明充分利用散射效应的成像技术可以实现透过散射介质或复杂介质成像,且具有超分辨的特性。本文在介绍散射成像基本原理的基础上,重点介绍了透过散射介质成像方法以及相关技术的研究进展,分析了散射成像尚存在的问题,最后对散射成像未来的研究方向进行了展望。

In practical optical imaging, light scattering phenomena cannot be avoided. Conventional optical imaging technologies, however, are less effective in solving the problems of wavefront distortion and image degradation, which are caused by scattering. Recent research results have revealed considerable evidence that the imaging technologies fully utilizing the effect of scattering can realize imaging through scattering media or other complex media and have super-resolution characteristics. This paper clarifies the basic principle of scattering imaging, focuses on the research progress of existing imaging methods through scattering media and related technologies, and discusses the current issues related to scattering imaging. Finally, potential research directions of scattering imaging are prospected.
