Laser Rangefinder
Hi,
I'm looking for a laser range finder that will accurately measure distance (~1-2mm) over a couple of meters. Its to be used in profiling scale models of hydraulic structures (jetty/breakwaters) and needs to have a narrow beam with (<5mm) so I cant use sonar and probably not IR. The Leica disto is a good example of what i'm after but it needs to have an interface to other hardware rather than a push button to scan. Although I'd love to spend the time to develop my own, it just not there so I'm after a quick to implement system. The trouble is there is either very expensive systems, or very dumbed-down ones used for construction.
Any ideas?

By using a wider laser/sensor separation, you should be able to attain a two-meter range. You'd have to experiment to determine what accuracy could be achieved. My recommendation would be to defocus the lens a little so you can interpolate the position of the centroid between pixels.
