What is the Laserlux?

It is a real time scanning Retoreflectometer developed for the purpose of providing simple, reliable, objective and inexpensive high speed marking surveys, needed for the management of highway infrastructure. The laser beam from the van and sweeps left to right across the pavement marking.

The beam reflects off the pavement and is sensed by a photo array. The geometry of the laser and photo array matches the standard geometry of the headlights and drivers eye perspective. The amount of laser light returned to the array determines the pavement marking retroreflectivity. The unit can be attached quickly to either side of the vehicle and can scan 2 lines at once. It can also scan different coloured lines as well.
