What sort of sensor is used in police laser detector systems?
Anybody happen to know what sort of sensor is used in systems that can detect police speed lasers?
Is it a phototransistor? a PIN photodiode? or what? They aren't terribly expensive, so I'm guessing there's not much to them.
From a few tests I've done, these systems seem to react very fast, too, so I'm guessing there's not much integrating going on. Do they just detect a sudden spike? Or a pulse rate?
Just curious,
Thanks.

That sounds kinda expensive. Like something they might sell at Starbucks. You sure it's not something more in the K-mart domain?
Go ahead..... waste it.... I dare you.
Perhaps a trained animal based detector??
