Journal ArticleDOI
Controlling waves in space and time for imaging and focusing in complex media
TL;DR: In this article, the authors used strongly scattering materials to focus, shape and compress waves by controlling the many degrees of freedom in the incident waves in complex media such as white paint and biological tissue.
Journal ArticleDOI
Adaptive optics via pupil segmentation for high-resolution imaging in biological tissues
TL;DR: An approach to adaptive optics in microscopy wherein the rear pupil of an objective lens is segmented into subregions, and light is directed individually to each subregion to measure, by image shift, the deflection faced by each group of rays as they emerge from the objective and travel through the specimen toward the focus.

Relay-Assisted Free-Space Optical Communication
Majid Safari,Murat Uysal +1 more
TL;DR: This paper considers an aggregated channel model which takes into account both path-loss and turbulence-induced log-normal fading in free-space optical systems operating in atmospheric turbulence channels and derived closed form expressions for outage probability of the relaying schemes under consideration.
Journal ArticleDOI
Guidestar-assisted wavefront-shaping methods for focusing light into biological tissue
TL;DR: Recently developed 'guidestar' mechanisms that provide feedback for intra-tissue focusing are summarized and potential applications of guidestar-assisted focusing include optogenetic control over neurons, targeted photodynamic therapy and deep tissue imaging.

Adaptive aberration correction in a confocal microscope
TL;DR: An adaptive confocal fluorescence microscope incorporating this modal sensor together with a deformable membrane mirror for aberration correction is demonstrated, which shows considerable improvement in contrast and apparent restoration of axial resolution.
