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

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 calused by reflection and back scattering,two framnes 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.

丝绸之路图像记忆——敦煌石窟朝鲜半岛人物形象阐释

前言敦煌石窟是'形象的历史'~1,敦煌壁画、彩塑、藏经洞绢纸绘画等图像资料是丝绸之路历史、文化、宗教、艺术交流的产物,是研究中古时期历史文明交融互动不可多得的珍贵史料。其中保存于唐五代宋洞窟壁画中的朝鲜半岛人物形象,是中古时期以图像形式保存下来的重要资料,值得作专题的研究。
