Non-invasive optical focusing inside scattering media is still a big challenge because inhomogeneous media scatter both incoming photons for focusing and outgoing photons for observation. Various approaches, utilizing non-linear fluorescence or ultrasound, have been reported to address this difficulty. However, implementation of these methods is complicated and highly expensive, as ultrafast laser systems or photo-acoustic equipment must be employed. Here, we demonstrate a wavefront shaping… Expand

Non-invasive super-resolution imaging through dynamic scattering media
This work demonstrates non-invasive super-resolution imaging through scattering media based on a stochastic optical scattering localization imaging (SOSLI) technique that utilizes the speckle correlation property of scattering media to retrieve an image with a 100-nm resolution, an eight-fold enhancement compared to the diffraction limit.

Image reconstruction and enhancement by deconvolution in scatter-plate microscopy.
This work investigated the capabilities of deconvolution for image enhancement in scatter-plate microscopy and obtained significant image enhancement both with means of inverse filtering and by applying iterative deconvolved algorithms. Expand
Noninvasive focusing through scattering layers using speckle correlations.
It is shown that the information obtained from speckle correlations can be used as a noninvasive feedback mechanism for wavefront shaping and this feedback is utilized to demonstrate non invasive diffraction-limited focusing of coherent light through thin scattering layers. Expand

Single-shot multi-view imaging enabled by scattering lens.
It is demonstrated that both stereo imaging with large disparity and up to seven-view imaging of a 3D object can be reconstructed from only one speckle pattern by deconvolution by utilizing the memory effect and uncorrelated point spread functions among scattering media. Expand
