semi OT: non contact distance measurement?

Hello everyone,
I'm looking for some type of accurate non-contact
(optical? acoustic?) measurement system that can read zero to 100 feet.
This thing will likely have to be able to resolve down to at least 0.1". Am
I dreaming? Leica makes a laser rangefinder that exceeds these specs (200K
US), but I know prices for this technology have come down drastically in
the last few years. Likely will use a stamp for the interface. Any ideas?

Thanks, Duncan

    Duncan,

    You might take a look here: http://www.rieglusa.com/ld90.htm

    I don't know about cost, but they have a model with 1cm accuracy.
    Resolution is often greater than accuracy...

    Thanks Mike, I was aware of the riegl laser units. Senix (www.senix.com)
    has ultrasonic modules with better performance, and they're pretty
    reasonably priced (ie. <$1000). These still only go to a tenth of an inch
    resolution - I was hoping for something better.

    Thanks, Duncan
