P3D Stereo X-Rays' Return.

[David Spacey <spacey@xxxxxxxxxxxxx>]

Hi All,

Last night "Tomorrow's World" (a *very* long running science and
technology show over here) featured stereoscopic X-Ray devices for airport
security.

The conveyor belt passed under two beams, natch, arranged in an inverted
V.  Presumably the computer allowed for the delay to get two views of the
same case.  The display looked like it was using a full-screen lcs system,
since the presenter and demo guy were using simple crossed-polariser
funnyglasses.  Hey, the presenter even knew they were crossed polarisers!

It was being presented as a faster and better way to identify "suspect"
packages.  In another demonstration it made it easier to locate contraband
once identified.  They didn't have to search the whole case for the gun,
they could see which pocket it was in.

Of course, the doubled X-ray dose means you wouldn't want your film to be
in there.
