I saw this article posted on physorg about MIT researchers discovering an improved method of obtaining high resolution 3D scans.
The article is linked with further details.MIT researchers have shown that by exploiting the polarization of light—the physical phenomenon behind polarized sunglasses and most 3-D movie systems—they can increase the resolution of conventional 3-D imaging devices as much as 1,000 times.

Thanks.
