A New Camera Can See Through Almost Anything, Including Human Tissue and Bones
When asked what superpowers they would like to have, many say the ability to see through things. Now, there may be a camera that could give people that gift.
Developed by Northwestern Engineering researchers, the new high-resolution camera can see around corners and through human skin and even bones. It also has the potential to image fast-moving objects such as speeding cars or even the beating heart.
The relatively new research field is called non-line-of-sight (NLoS) imaging and comes with a level of resolution so high that it could even capture the tiniest capillaries at work.
“Our technology will usher in a new wave of imaging capabilities,” said in a statement the McCormick School of Engineering’s Florian Willomitzer, first author of the study.
The new technology could be used in applications ranging from noninvasive medical imaging, early-warning navigation systems for vehicles, and industrial inspection in tightly confined spaces. But how does it work?
It essentially intercepts the scattered light coming from an object in order to reconstruct the inherent information about its time of travel to reveal the original object. The scientists compare it to shining a flashlight through your hand.
In this case, you should see the bone in your hand but the light coming through scatters the bone image resulting in just a large dot. NLoS can capture this scattered light and reconstruct it into a coherent image.
