       Anyone know what they're using as a detector?  I'm building a laser
rangefinder for robot vision, and I'd like to know what these guys use.
PIN diodes don't put out much output and avalanche diodes are too nonlinear
for use when the beam is dimmer than the ambient light.  So what do they
use to get that kind of S/N?
