The wavefront is scrambled when coherent light propagates through a random scattering medium and which makes direct use of the conventional optical methods ineffective. In this paper, we propose and demonstrate a structured light illumination for imaging through an opaque scattering layer. Proposed technique is reference free and capable to recover the complex field from intensities of the speckle patterns. This is realized by making use of the phase-shifting in the structured light illumination…

Holographic imaging through a scattering layer using speckle interferometry.
It is demonstrated that under suitable conditions, it is possible to perform imaging to reconstruct the complex amplitude of objects situated at different depths and to retrieve the interference fringes projected behind the scattering medium.
Lensless complex amplitude image retrieval through a visually opaque scattering medium.
A lensless configuration is implemented which eliminates any possible aberration effects associated with optical components, and this further has promising applications where the use of imaging optics is not feasible.

A wavefront division multiplexing holographic scheme and its application in looking through diffuser
We present a spatial light modulator (SLM) assisted compact holographic method and illustrate its application by imaging through a random scattering medium. The merit of the proposed method is
Imaging optical fields through heavily scattering media.
A remarkable result based on speckle correlations over incident field position is reported that demonstrates that the field incident on a heavily scattering random medium can be obtained using a method that is not restricted to weak scatter and is, in principle, independent of the thickness of the scattering medium.
Optical reciprocity induced wavefront shaping for axial and lateral shifting of focus through a scattering medium
Light propagating along a reversed path experiences the same transmission coefficient as in the forward direction, independent of the path complexity. This is called the optical reciprocity of light,
Single-pixel digital holography with phase-encoded illumination.
This work demonstrates imaging of complex amplitude objects through digital holography with phase-structured illumination and bucket detection and shows that the system is well-fitted for transmission of the object information through scattering media.
Measuring optical transmission matrices by wavefront shaping.
This work introduces a simple but practical method to measure the optical transmission matrix (TM) of complex media and demonstrates the generation and linear combination of multiple foci on demand through the complex medium.
Digital optical phase conjugation for delivering two-dimensional images through turbid media
This work presents a simple and robust digital optical phase conjugation (DOPC) implementation for suppressing multiple light scattering, and demonstrates its turbidity-suppression capability by reconstructing the image of a complex two-dimensional wide-field target through a highly scattering medium.
