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.
No. Reading is useless without understanding. The OP was correct in asking. Your hand is not opaque, it is translucent.

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.

Nowadays, "illegal" doesn't mean you can't do it -- it's just not admissable in court.
You can get your last dollar they still do it, but then need to come up with a pretense for anything involving the courts.
Remember, they can now slap a GPS device onto your car with absolutely no court oversight. Just imagine all of the illegal things they do and cover with sealed court proceedings.
