By cleverly analyzing the results, the algorithm can deduce the shape, size and layout of a room, as well as pick out in the presence of objects or people. The results are displayed as a video feed which turns the echo data ...

Temporal control of light echoes

Scientists at Paderborn University, the Technical University of Dortmund and the University of W├╝rzburg have for the first time used laser pulses to precisely control photon echoes, which can occur when light waves superimpose ...

Why bats fly into walls

Bats excel in acoustic perception and detect objects as tiny as mosquitoes using sound waves. Echolocation permits them to calculate the three-dimensional location of both small and large objects, perceiving their shape, ...
