[rec.autos] laser speed measuring device

The probably belongs in sci.electronics, but since in the next year cops
across the country are going to start shooting laser beams at us, I would
be concerned about eye safety.  The "eyesafe" frequencies in the IR are > 1.4
microns.  International Measurement may or may not have taken this into account
