Scientists Invent Camera That Can See Through Solid Objects

Northwestern University engineers have invented a powerful holographic camera that can see through almost anything including fog, corners, human flesh and bones.

The camera relies on synthetic wavelength holography which works by scattering laser light onto hidden objects then bouncing it back to the camera, where an AI reconstructs the signals to show the hidden object.

This new invention is likely to find useful application in non-invasive medical imaging since it can see through a heart beating through a person’s chest.

It can also see fast moving objects such as cars moving through corners and hence can be used in early-warning navigation systems for automobiles.

“Our technology will usher in a new wave of imaging capabilities,” Florian Willomitzer, assistant professor at the McCormick School of Engineering and lead author of the study, said in the release. He added that the camera method “could be applied to radio waves for space exploration or underwater acoustic imaging.”

The technology is still in its prototype stage and might help prevent car accidents in the future as self-driving vehicles become more and more prominent.
