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 ...

which can see through walls and other obstructions but generates rudimentary, low-resolution images, or cameras and LiDAR, which provide detailed images but perform poorly in difficult situations.

Imagine being able to capture a high-resolution 3D image of a distant object—even a human face—through fog, foliage, or ...
