In general round surfaces are much better laser targets then flat surfaces. This is why headlights (often) are good targets for laserguns. They reflect well, and somewhere on its round area there will be a spot that returns the laserlight back to the gun.
A flat front normally is easier to protect, because the lasergun gets less usable reflection from it......
Man, I need to buy a black C4 corvette! That would be the ultimate in laser protection. Totally flat hood, black color, no font plate and the retractable headlights would be nuts!! The cops wouldn't know WHAT to do with that laser beam.
LIDAR needs a certain amount of light reflected back at it. Flat fronts reflect more light TOWARD the gun, whereas rounded fronts have more bits that would cause a reflection, but less overall area reflecting at the gun.Quote:

Unlike radar, lidar is a very narrow and controlled beam. You're thinking of RADAR.
Look at yourself in a mirror, and then turn the mirror around a little bit. There is only one position where you can look into your own eyes. A flat mirror potentially is the best reflector for a laser, but only when it happens to be at exactly the right position. In all other cases, the light will go somewhere else. REALLY! :):)
OK. Sorry for this grammar police post, but this is a pet peeve of mine. The word you are looking for here is "definitely". The word "defiantly" means to boldly resist. It's root word is "defy".Quote:

I have had experience with cars with flat surfaces that are contradicting your experience.
A few years ago, we experimented here a lot with destroying the retro-reflecting capabilties of rear-reflectors and license plates.
We basically repainted the license plates in a normal color yellow very close to the original retro-reflecting yellow, and destroing the reflectors from the inside using a dremel minidrill to f**k up the facets of the reflector. (You couldn't see it from the outside, but the retro-reflecting effect was gone)
That left us with a naked rear of the car. The end result was that most cars we tested with were very difficult to laser from the rear, but much easier to laser from the front.
(also "modified" license plate in the front) The headlights where the remaining big problem. We also used IR/flash photography to show remaining reflecting surfaces. There were many more hot spots in the front than in the rear.
On the other end for example: Some flat surfaces scatter the light maybe 10-20 degrees (The ideal flat mirror is 0 degrees) If that surface is less than 20 degrees off from the ideal position, it becomes an easy target. (A much better target than a flat mirror in the same position) Again there are many parameters that will influence the end result................
Fact is: If you glue a flat mirror on the back of a car, it will become almost impossible to laser it. (Except from one angle)
Maybe the best answer is that flat and highly reflective surfaces are very difficult laser targets. And flat surfaces that scatter light just enough to compensate for the angle are easy targets.

I live in a state where jammers are not legal so I was hoping for them to be a bit more hidden than they are. Do you guys think I'll be OK keeping them mounted where they are? Or is it unbelievably obvious? Would it effect the way they operate if I were to move them back into the vent another 3/4 inch? They just seem like they're sticking out pretty far.
What do you think?
