Seeing through dynamics scattering media:Suppressing diffused reflection based on decorrelation time difference
《Journal of Innovative Optical Health Sciences》2019年第4期67-73,共7页Honglin Liu Xin Wang Jingjing Gao Tingyi Yu Shensheng Han 
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 reflect...
