Laser positioning

Hectic week at the N.E.C. Birmingham with a stand at a trade show...

One of our high-tech laser widgets...

A little larger than a fag packet, this laser scanner "reads" a continuous code strip and knows where it is to within 1 millimetre anywhere along the strip, up to 10 kilometres long...

The London Eye has a previous model, so the brains of the machine knows - with great accuracy, exactly where it is in it's rotation.
