  • Light propagating through a scattering medium exhibits correlations in the transmission matrix. A theoretical and experimental study uncovers intensity correlations that survive multiple scattering, which could be exploited for imaging.

  • Broadband energy can be delivered to extended targets deep inside a multiple-scattering system, paving ways for using broadband, partially incoherent light in a wide range of applications, such as deep-tissue imaging, laser therapy and optogenetics.

  • High-resolution single-photon imaging is challenging due to complex hardware and noise disturbances. Here, the authors realise simultaneous single-photon denoising and super-resolution enhancement by physics-informed deep learning, with a physical multi-source noise model, two single-photon image datasets, and a deep transformer network.

  • Scientists introduce an approach, time reversal of variance-encoded light (TROVE), that can demix spatial modes within an ultrasound focus inside scattering media, breaking the resolution barrier imposed by the ultrasound. Optical focusing and imaging with diffuse light at a speckle-scale lateral resolution of ∼5 µm is achieved.

  • A wide-field, high-resolution imaging scheme that offers enhanced depth of field is demonstrated. The approach relies on stitching together time-multiplexed images in Fourier space.

  • The definition and reporting of spatial resolution for coherent imaging methods varies widely in the imaging community. We advocate the use of a standard spoke-pattern imaging target and the mandatory inclusion of information about underlying a priori assumptions.

  • Ptychography computationally reconstructs high-resolution images from overlapping diffraction patterns, recovering both amplitude and phase information. This Primer covers the technique’s principles, diverse wavelength implementations from optical to electron regimes, advanced reconstruction strategies and applications ranging from live cell imaging to atomic-resolution materials characterization.
