Visible Light 'X-Ray' Sees Through Solid Objects
disco_tracy writes "Some day we may not need X-rays to see inside people, thanks to a new way to decipher light that passes through opaque surfaces. Normally visible light becomes too scattered to detect after passing through opaque surfaces. But scientists in France have developed a way to reconstruct images from light passing through such surfaces by deciphering just how the material makes the light scatter. In the short term the research will help improve the strength of telecommunications signals and fiber optics cables, but years from now the technology could supplement or even replace traditional ultrasounds for baby imaging and X-rays for weapons detection at airports."
How does visible light make its way through an opaque object?
I want to delete my account but Slashdot doesn't allow it.
I know you aren't supposed to read TFA, but "'It's like putting a flashlight behind your hand,' said Sylvain Gigan... 'You cannot see an image, but you can still see a faint glow.'"
I think it would help if TFA included an actual example image, and not just a photo of someone holding their hand up behind a shower screen and a note to the effect that the actual technology might produce images sort of like that one.

It just so happens that your object here is only MOSTLY opaque. There's a big difference between mostly opaque and all opaque. Mostly opaque is slightly transparent. With all opaque, well, with all opaque there's usually only one thing you can do.
