  Optical imaging through complex scattering media is one of the major
technical challenges with important applications in many research fields,
ranging from biomedical imaging, astronomical telescopy, and spatially
multiplex optical communications. Although various approaches for imaging
though turbid layer have been recently proposed, they had been limited to
two-dimensional imaging. Here we propose and experimentally demonstrate an
approach for three-dimensional single-shot imaging of objects hidden behind an
opaque scattering layer. We demonstrate that under suitable conditions, it is
possible to perform the 3D imaging to reconstruct the complex amplitude of
objects situated at different depths.
