Saw a possible speed trap Saturday evening

I saw a number of state troopers on 106 standing outside their cars aiming at cars with what looks like a miniature vdeo camera. It is definitely not a radar detector. Can Skip tell us what it might be?

It's a handheld instant-on LIDAR (or Laser if you prefer) unit. Unlike the traditional Ka band units installed in their cruisers, using the device you saw with its integral aiming allows Troopers to "paint" and pick out individual vehicles, even in moderate traffic, from very great distances. The NHMP unit pictured above is just a slightly different version of what NHSP is now using on the highways, along with a growing number of local & county departments.
