All the professional ones use essentially the same concept. Laser
interferiometry to determine distance, and some kind of computer controlled
most to increment the laser head. A series of points are the raw data.
Filtering is necessary (there are false points). Building a CAD model from
the data is not trivial, but it depends on what you are using it for.
Hard to see how it relates to LEGO robots, though. These are expensive. I
would love to have any kind of precision distance sensor for the RCX, but as
these are large data sets, it just doesn't seem practical right now.
