Here is a blurb:

Georgia Institute of Technology scientists say they've created a prototype device that can block digital video cameras from working in a specific area.

Here is the full story:

Wouldn't work on a SLR since the sensor is only visable for a fraction of a second.  On longer shutters it might effect but depends on how fast their processor is to detect the sensor amoung all other shiny objects.  Also not sure about beaming a blinding light at people (could be some good personal injury cases in the US)

I would agree, the explanation was brief and non-technical. But I doubt it could detect and direct a light source under 1/250 of a second. Which is why it specifically mentioned digital cameras and not film cameras. If it could do it under 1/250 of a second, then it would work for all cameras (including film).

There is a more detailed article out there somewhere that I have read.  It doesn't work on film cameras either as it detects the CCD (and CMOS??) sensor.  Basically it detects reflective surface, then analysis it for the specific characteristics of the sensor, and if it thinks it is a sensor, then it shoots white light (maybe upgraded to laser but that would hve more issues be injury claims).

Using a laser isn't a problem. Despite what a lot of people think, there are plenty of lasers that could be used that are low enough in power that couldn't damage the human eye. In fact most pointers can't damage the human eye unless you leave it shining in someones eye for a long period of time. I still seriously doubt whether it could be used against a SLR.
