Matrix-based imaging through dynamic scattering

A matrix-based imaging method enables high-resolution imaging through dynamic scattering by exploiting a mathematical equivalence to static media, allowing state-of-the-art methods to recover images from a few frames in coherent and incoherent setups.

Focusing and compression of ultrashort pulses through scattering media

Scientists show that spatiotemporal focusing and compression of non-Fourier-limited pulses through scattering media can be achieved by manipulating only the spatial degrees of freedom of the incident wavefront. This technique is potentially attractive for optical manipulation and nonlinear imaging in scattering media.

Controlling light in complex media beyond the acoustic diffraction-limit using the acousto-optic transmission matrix

Various techniques combine light and ultrasound to study the inside of strongly scattering samples, beyond the reach of purely optical imaging. Here, Katz et al. introduce the acousto-optic transmission matrix framework that allows to control and focus light beyond the acoustic diffraction limit.

Real-time wavefront shaping through scattering media by all-optical feedback

The self-organization of many laser modes in phase and frequency realized by minimizing radiation losses in a cavity enables the complex wavefront required to focus light scattered by turbid samples to be generated on sub-microsecond timescales without employing electronic feedback, spatial light modulators or phase-conjugation crystals.

Image-guided computational holographic wavefront shaping

Guide-star-free imaging through turbid media is achieved by computational back-projection and averaging of as few as 25 holographically measured scattered fields under a random unknown illumination.

Flexible-type ultrathin holographic endoscope for microscopic imaging of unstained biological tissues

Lensless fibre endoscopes are minimally invasive, but are often rigid and require calibration and fluorescence labelling. Here, the authors present a flexible endoscope based on a bare fibre bundle and a lensless Fourier holographic imaging configuration to detect weak reflections from unstained biological tissues.

Looking around corners and through thin turbid layers in real time with scattered incoherent light

Researchers show that wavefront shaping enables not only real-time widefield imaging through turbid layers with both coherent and incoherent llumination, but also the imaging of objects outside the line-of-sight using light scattered from diffuse walls.

Real-time holographic lensless micro-endoscopy through flexible fibers via fiber bundle distal holography

Fiber-based micro-endoscopes are minimally invasive, but 3D imaging is limited by the need for bulky optical elements or rigid fibers. Here, the authors demonstrate holographic imaging through flexible and dynamically bent multi-core fibers by adding partially reflecting mirror to the distal fiber-tip.

Passive optical time-of-flight for non line-of-sight localization

Optical imaging through barriers is highly desired for many applications. Here the authors demonstrate a time-of-flight technique that can passively localize light sources and reflective objects through diffusive barriers and around corners.

Golgi organization is regulated by proteasomal degradation

Correct Golgi assembly is important to cellular homeostasis but regulation of its structure under stress remains unclear. Here, the authors identify stress-induced degradation of GM130 by Golgi-localized 26S proteasomes, leading to Golgi dispersal.

Imaging in complex media

Seeing—and consequently imaging—through turbid media such as fog is a difficult task, as multiple scattering scrambles the visual information. This Review summarizes techniques that physically or computationally reconstruct the images.

Acousto optic imaging beyond the acoustic diffraction limit using speckle decorrelation

Acousto-optical imaging (AOI) is a technique used for deep tissue microscopy in biomedical applications. The authors use statistical approaches of super-resolution optical fluorescent imaging allowing them to realise high resolution AOI with speckle decorrelation in a much shorter time.
