摘要：

We propose a scheme to detect the diffusive cloak proposed by Schittny et al. [Science 345, 427 (2014).]. We exploit the fact that diffusion of light is an approximation that disregards wave interference. The long-range contribution to intensity correlation is sensitive to the locations of path crossings and the interference inside the medium, allowing one to detect the size and position, including the depth, of the diffusive cloak. Our results also suggest that it is possible to separately manipulate the first- and the second-order statistics of wave propagation in turbid media. (C) 2016 Optical Society of America
