Police Lazers

[scumdog]

how much do you wanna bet dude....

Your bosses been talkin crap AGAIN

I ain't heard a peep from his bosses, when did you?????

[Hammer]

So what is it with the lazer cops?
I have seen several of late when I am clearly speeding. But they don't seem interested.

Now I am not complaining one bit, just wondering why it is they leave me alone.
Like last night, left late and in a bit of a hurry to get to Motohaus. Doing 135 on the motorway come over a slight brow and hello mr plod with a lazer.
On with the picks.
He puts the Lazer down as I get closer and I am thinking he is about to follow, I'm screwed. But hey they were being nice yet again.

Do they need time to get a lock?
Do they need a constant speed during this time?
Is it hard to get a fix on a bike?

How do you know it was laser? Did you have a radar detector that went off. Either way you that was lucky - usually with laser you get less warning time than Ka so when it goes you have to hit the anchors hard. They will pick up a bike. Sounds like you lucked out.

Laser jammers, me thinks, not radar jammers. Two different beasts. Don't think you can jam radar unless you've got something like an Aegis cruiser to work with. Laser's (maybe) a different matter.

EDIT- Quote, from the site you linked

Active Laser Jammers


Active Laser Jammers

Laser is a beam of light in the infrared spectrum. When officers use a laser gun, they target individual cars that they want to obtain a speed on, and active the gun by pulling the trigger.

The beam of light that strikes your car is very narrow and reading the officer gets is instant.

There are several active laser jammers that are very effective in jamming police laser, they are:

BLINDER X-TREME
blinder xtreme

The Blinder M-20 and M-40 are perhaps the most effective active laser jammer made today. In testing by SML at the 2004 radar detector shoot out, they jammed 100% of all the police laser guns.

A radar jammer would be possible, just to give false returns. Stealth is almost impossible to do for a bike without unorthodox designs.

A powerful radar emitter of the right frequency etc should be enough to kill the radar transmitters return/reflection.

Same concept as a laser jammer.

Hey... wonder if you could fit a bike out with that stealth technology stuff like they use on the B52 or whatever it's called?

That'd be pretty sweet eh?

head light is a big reflector no?

[Zapf]

There were 2 cars between me and cop car.......reckon the cars were doing over 100.....I just slowed down......not slow on the SV'S engine braking

There is no way he can get your speed using a laser gun when there is clearly 2 cars in the line of sight. right?

[Pixie]

Laser jammers use laser diodes pointing out the front of the bike (hopefully right at the laser gun) and send out a stream of pulses at a much higher rate than the 1kHz the police lidar uses. This is interpreted as noise.

Not necessarily laser diodes,
The Blinder I use has 9 IR LEDs pulsed at 4 Mhz And is proven effective,
(tested against a privately owned laser gun)

Hmm, depends on the angle but with the sights on the laser I wouldn't put money on them NOT being able to pick you out, no sir!!

[Zapf]

The infrared light will relect off any surface (some more than others), but most surfaces scatter the light and it is very weak by the time it gets back to the laser gun. Retro-reflectors (like the white or red rectangles fitted to the front and back of bikes, and number plates) direct all the energy they receive right back at the source.

So Matt black paint with high rubber content.... who wants a spongy matt black bike?

Saying that your a cop is one thing, however "You actually get a kick out of your "little" laser gun,,

Only when its aimed at special people, like you.

Yep..........................

and the cop car was so far away that all I saw was the flashing lights when I came around the bend.......assume it was the 'Hawk' on the car....I dunno whether he could have got me and I have given up........don't tell me about hearing, sent re-hearing form in December, have not heard back and I lose 35 points in May and if worst comes to worse I will have no probs getting a day licence so not worth the stress anymore......

[sAsLEX]

Aegis cruiser (is that that british one??) would probably do it lol

Never heard of a laser jammer, are they out there?

Would be Mighty Old american that one, and a nice piece of kit.

Quite common, and probally not that hard to make.

I would also hazard a guess to say that Jammin a radar signal from the 5-0 would not be hard either as they wouldn't be freq hopping or nothing fancy, only issue is it is illegal to transmit at the powers you need.

Another Q, do the police have a license to transmit their radars?

[The Stranger:Me]

How do you know it was laser?

Actually, good point. I must admit, I had thought that all the hand held units with the little like gun sight on the top were lasers as I had had a play with one once at a demo the cops did at MOTAT. But of course assumption is the mother of all f&%k ups, so I may be talking crap.

Did you have a radar detector that went off. Either way you that was lucky - usually with laser you get less warning time than Ka so when it goes you have to hit the anchors hard. They will pick up a bike.

No, no radar detector, well not an electronic one anyway. Mine is tucked safely in my helmet.

Sounds like you lucked out.

Well yeah, but the thing is this. I have been so bloody lucky lately that I can't believe it. So I think there is more to it than just luck and discretion. Though if I am wrong about the discretion a big big thank you to all the Police out there. You guys really rock.

I ALWAYS focus on the vanishing point when I ride and observe the the area in front of me with peripheral vision.
I just wonder if that contributes to the luck.

Of course you could always take scummy's advice and simply not speed. But it's easier for him, he has a Harley.

Vehicle colour makes a difference too. It's not called 'ticket red' for nothing.
Tests in the States showed the hardest cage to get a reading on was a black mid '90s Camaro with the lights retracted. (It had no front plate)
