Researchers have designed a single-photon time-of-flight LiDAR system that can acquire a high-resolution 3D image of an object or scene up to 1 kilometer away. The new system could help enhance security, monitoring, and remote sensing by enabling detailed imaging even in challenging environmental conditions or when objects are obscured by foliage or camouflage netting.

    superconducting nanowire

    Okay, so not room-temperature.

    To reduce noise levels, the detector was cooled to just below 1 Kelvin

    Jesus.

    1 ms per-pixel acquisition time

    Yeah, that tracks.

    The fact this works in daylight is still mindboggling. Could this be used for astronomy? If they can bump up the distance by a few orders of magnitude, maybe relax their superconductors to merely LN2 levels, we could image the shit out of Venus.
