(Phys.org) —Currently, precision laser ranging is limited to the Earth-Moon distance. These systems are based on passive laser ranging, so that the signal deteriorates as 1/R4 over distance R. In a new study, physicists have ...
Researchers have developed an easy-to-build camera that produces 3D images from a single 2D image without any lenses. In an initial application of the technology, the researchers plan to use the new camera, which they call ...
