they are testing a device, that can send beams of "white light" to disable/render useless
CCD (camcorders,phones) to keep people from pirating their movies
at the theatre
only 1 problem....
""We need to make our system work well enough so that it can find a dot, then test to see if it's reflective, then see if it's retroreflective, and then test to see if it's the right shape.""
sounds like an eyeball would be the perfect target (at least the iris and pupil)
its about the same as the lense (dot) on most camera phones and point+shooots
does anybody out there in theese fields know about white light,reflective/retroreflective
or the eyes...

And finally, screw them... I'm not having some machine scan the room to see if I'm video taping the movie. Who knows what else they would scan for... if you are eating popcorn or drinking soda... are you almost out of candy? Are you making out in the back?
I would absolutely refuse to go to a movie theatre if this scanning technology were ever implemented.
The technology works by looking for the digital camera's image sensor known as a charge-coupled device (CCD).
These silicon sensors are retroreflective, which means that they reflect light directly back to its origin, rather than scattering it.
Some road-signs and vehicle licence plates are also retroreflective.
At present, the industry mostly relies on the alertness of staff at cinemas to spot people filming.
However, Disney took this one stage further in 2003 when it issued security staff with night vision goggles and metal detectors, ahead of screenings of the animated movie Finding Nemo.

Why would the 'light' beamed have any effect on the eye?
The frequency used is that which is used by cameras to judge distance.

There seriously is nothing to be worried about.
No the eyes aren't the correct material to attract this system, nor is the beam thats sent out even visible to the huma eye.
The frequency used is that which is used by cameras to judge distance. Its sent out to confuse the camera as to the whereabouts of its target.
