An ultrafast optical shutter was used to image ultrasmall objects hidden behind scattering walls by a procedure that selects in time the ballistic component and rejects the scattered diffusive light. Scattering walls used in this experiment included human breast tissue, chicken breast tissue, and a water suspension of polystyrene particles with scattering coefficients up to 21.7. Submillimeter resolution was achieved for two-dimensional ballistic images of a single point, a double-point fluorescence source, and a bar test chart in or behind these different turbid media.
采用超快光闸，通过选择弹道分量并排除散射漫射光的方法，对隐藏在散射墙后的超小物体成像。本实验中使用的散射壁包括人体乳腺组织、鸡乳腺组织和聚苯乙烯颗粒的水悬浮液，其散射系数高达 21.7。在这些不同的混浊介质中或其后，实现了单点、双点荧光源和条形测试图表的二维弹道图像的亚毫米分辨率。
