‘Superman’ vision penetrates opaque glass

It’s not quite X-ray vision, but a way has been found to transmit simple images through opaque objects using ordinary light – and physicists have used the method to project an image through glass covered in thick paint.

By reverse engineering the scattering process, the team were able to reconstruct an image from the light that had passed through the opaque paint layer. That scattering is complex, but it’s also predictable: the same light wave will always be scattered in the same way.
