DPRG mailing list archives: [DPRG] Basic Laser Range Finder

Sun Sep 2 11:56:56 CDT 2001

The Circuit Cellar article "A Low Cost Laser Range Finder" was published in
1994.  It was written by Tom Ward of Brisbane Australia.  I have a
preliminary version of the article instead of the published version, so I do
not know what month it was published.  The range finder used about $150
worth of parts and used triangulation.  It is an excellent design and the
article has full details including source code.  Since it was designed for a
micro mouse it has a very short maximum range, but could be easily changed
for longer range.

Sharp Electronics Corporation makes some cheap triangulation range finders.
Uses an LED instead of a laser.  Cost is about $15, maximum usable range is
about 30 inches.
