Behind windshield laser jammer?

[NormSky]

Because exterior mounted laser jammers deteriorate over time will we ever see interior mounted jammers? Or will laser jammers always need to be mounted near the most reflective parts?

Who knows what the future will bring, but I don't see it in the foreseeable future!

X2. I can't even imagine the sensor optics needed to make sure they pick-up all laser hits, then the brute power they would have to push out to make up for their distance away from virtually every hard-point on the front-end of a car, and make it through (what might be a dirty) windshield... I don't think complex algorithms can make-up for power (or lack of) in that case.


Granted... I think current gens of high-end jammers (Read: Blinder/LI) have been holding up very well for people, so I don't see the big issue... ALL electronics fail over time (look at our internally mounted radar-detectors)!



Lastly... there could be a system coming in the future (add-on to current jammers) which might allow us to mount the head away from "the worst" the road has to offer... not sure how much we can talk about it... so that is a feasible alternative methinks.

Who says they deteriorate?

I think he is referring to the lenses. The way they get scratched/pitted/hazy over time as road debris and grime effect the lenses.

[NormSky]

Exactly! The led/diode don't wear out but using them outside will eventually decrease performance. If it could be rugged behind the wipers it'll have a clear cue all the time.

Your concern is understood. But the problem is that Lidar pulses will hit & bounce off the forward most surfaces before it hits your jammers detector (if mounted in a location like you are thinking of). And timing is critical. The jammer has to read the pulses, interpret them, lookup the proper jamming algorithm then fire it's own pulses. The further forward the heads the more likely they will jam in time and prevent PT.

Blinder makes a head with a replaceable Lens. An Allen Key and 2 screws are all you need to replace the lens housing. Replacement lenses are inexpensive and easy to replace.

^ what he said. The shots will be at the front of the car by the plate most of the time. The jammers need to go where the shots are made

Exactly. At the speed of light, the return pulses from the gun will be received before the jammer pulses, which are a good four feet farther away, if behind a windshield. Perhaps an 'always on' device would solve this problem, but that bring forth a whole new set of problems.

So given this, does this mean that "further forward" is always better, for instance on a car with a slanted nose?
