Does anyone have any information on the theory behind a laser range finder? I assume it works by sensing the phase change on the returning reflected beam, but I'm not sure of all the smaller details. Also, does anyone have any information on constructing such a device at a minimal cost. (what would a minimal cost really be?) I'm looking for a device to mount on a mobile robot as a obstacle detection device. ----Richard Zimmerman (rsz1@cornell.edu)
