    Three-dimensional imaging using a frequency–angular resolving and frequency-modulated continuous-wave LiDAR enabled by a chip-scale acousto-optic beam-steering device has been demonstrated, with the simplicity and low cost of the device making this a promising technology.

    Lithographically patterned perovskite nanocrystal arrays were used to determine radiation vectors from X-rays to visible light and the emission colours of the nanoparticles was used to create images of three-dimensional objects and for phase-contrast imaging.

    A meta-imaging sensor detects an extra-fine 4D light field distribution using a vibrating microlens array, enabling high-resolution 3D photography up to a gigapixel with fast aberration correction, demonstrated on a telescope aimed at the Moon.

    The strong interaction of coherent free electrons with a photonic-crystal cavity enables the measurement of the lifetimes of the cavity modes and provides a technique for multidimensional near-field imaging and spectroscopy.

    A massively parallel coherent light detection and ranging (lidar) scheme using a soliton microcomb—a light source that emits a wide spectrum of sharp lines with equally spaced frequencies—is described.

    A vibrational spectroscopy technique that measures the electric field emitted from organic molecules following infrared illumination allows their molecular fingerprints to be separated from the excitation background, even in complex biological samples.

    A faint penumbra in a photograph of a diffuse surface enables recovery of the position of the object creating the penumbra and an image of the scene behind it.

    The response of a ternary, parity–time-symmetric system that exhibits a third-order exceptional point increases as a function of the cube-root of induced perturbations.

    A small-angle X-ray scattering computed tomography method that reduces the amount of data that needs to be collected and analysed to reconstruct the three-dimensional scattering distribution in reciprocal space of a three-dimensional sample in real space is demonstrated by measuring the orientation of collagen fibres within a human tooth.

    A technique based on compressed imaging with a streak camera is reported that can videotape transient events in two dimensions with temporal resolution down to tens of picoseconds, and its usefulness is demonstrated using single laser shots applied to a variety of physical phenomena.

    Here, using two-photon phosphorescence lifetime microscopy, the local oxygen tension in the bone marrow of live mice is found to be quite low, with spatiotemporal variations depending on the blood vessel type, distance to the endosteum, and changes in cellularity after stress.
