Progress and Prospect of Scattering Imaging
Scattering media exist widely in our daily life. Imaging through the scattering media presents important scientific significance and large application value in medicine, autonomous driving, national security, and other fields. Here, we briefly review the current progress in scattering imaging and analyze the scattering characteristics of media via distinguishing the ballistic light and the scattered light. Existing scattering imaging techniques are divided into two categories: methods that utilize the scattered light and approaches that separate the scattered light from the ballistic light. Two groups of methods that exploit scattered light are summarized. They analyze the spatial characteristics of scattering media and model the light propagation in the scattering media, respectively. Also, the spatial or temporal separability between the scattered light and the ballistic light is introduced. The scattering imaging techniques are compared in terms of illumination, complexity of imaging devices, prior information dependency, type and strength of scattering media, and filed of view. Finally, the development trend is forecasted.
