Physicists in the UK and Canada claim to have demonstrated for the first time how a spinning medium can rotate a transmitted image. According to the researchers, the phenomenon could be used to encode images with extra data.

It has long been known that a moving medium can shift the position of passing light. The reason is that the light's photons can be absorbed by the medium's atoms, which jump into a higher energy state as a result. A moment later, these atoms return to their original state, re-emitting the photons. But by this time the atoms have moved slightly, so the photons continue their path from that new position.
