Laser Calibration?
This past Sunday morning, a friend of mine got a ticket northbound on I-5
just south of Chehalis, WA. The cruise control was set at 72 mph (digital
speedometer). Evidently, there was a trap set with an officer using laser
positioned on an overpass, and several State Patrol cars waiting on the
on-ramp. The officer said he was doing 80 mph, and even though my friend
tried to plead his case, he still received an $85.00 ticket. As he was
going through the speed trap, a car passed him in the fast lane.
Questions: I believe the laser gun works by way of the Doppler Shift
principle; is it possible for the detector to be that far off? Is optics
misalignment a possibility where the car that was picked up was the faster
one next to him? (BTW, today he is having is speedometer calibrated.)
Thanks for your help...
