One of these, near the bottom of the page:

It's pretty complicated though. i think a device of this type *might* be what the surveyors use?

Do a Google search for laser interferometry distance measuring and you might be able to find something better.

If it's falling apart it's a mechanical problem. If it's spewing smoke it's a electrical problem.
If it's rampaging around destroying things it's a programming problem.

Re: Laser Rangefinders

Try looking looking on Globalspec for time of flight sensors. Even raw moduals will cost over 100$.
