I don't know if the technique is used in America but the speed cameras in
the UK are triggered by radar but produce evidence by taking two pictures
illuminated by two strobe pulses timed about 150ms apart. Stripes are
painted across the road spaced so that between flashes a vehicle will
traverse one stripe pitch for every 10mph.If the pictures show you have
traversed more than 7 stripe pitches (on motorways)you will receive copies
of these photos together with a summons to appear in court.

Hi All,
I apologize for being off subject but I was driving to work and
noticed aCalifornia Highway Patrol officer on the opposite of the
freeway an about 500 yards away. What brought him to my attention was
what appeared to be a strobe light that was flashing. I have been
thinking about and I was wondering if the new radar has some ways of
taking pictures or if the strobe light really is the radar source. Any
help would be appreciated.
Thanks
Jim Freeman
