Seeing through dynamics scattering media: Suppressing diffused reflection based on decorrelation time difference

Journal of Innovative Optical Health Sciences,Volume 12, Issue 04, July 2019. We observed a phenomenon that different scattering components have different decorrelation time. Based on decorrelation time difference, we proposed a method to image an object hidden behind a turbid medium in a reflection mode. In order to suppress the big disturbance caused by reflection and back scattering, two frames of speckles are recorded in sequence, and their difference is used for image reconstruction. Our method is immune to both medium motions and object movements.
