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.
