How Do Laser Jammers Work

Ah indeed, the question everyone’s mind! Just how do do laser jammers work? Do they work? How can they? You might have a friend who has fitted laser jammers on his vehicle, or you have often seen them on the BMW before you in traffic. Do laser jammers actually work?, people ask. How's that actually legal?, they postulate.

Laser jammers do work, and in a few states they may not be legal! In many US states, on the other hand, they are really as lawful as radar detectors.

Overall, police laser (LIDAR) guns determine speed through the use of infrared light to determine distance a few hundred times (in only a couple of seconds). The genius of police laser guns, compared with radar guns, are how the laser beam is concentrated onto such a small area that it can only focus on one car or truck at any given time. Police officers want to be capable of identify one exact automobile, and the laser gun's tiny beam lets them accomplish that. Light beams broaden when they travel; they may start as small as a pin when they exit the laser gun. Even so, even after 1000 ft, the beam is merely about six feet wide, still sufficiently small enough to focus on an individual car or truck.

Simply, the laser jammers simply shine back light at the laser gun! The laser gun does not have any idea of understanding which light it sent, and which light the laser jammers are broadcasting, consequently it can't get a speed reading. Of course, the light must be the same type of light emitted - in this case, infrared light at a wavelength of 904 nanometers (nm). In addition, it can't be just as bright as the laser gun itself, it must be brighter - much brighter! Just think that someone is shining a flash light towards you in darkness. You then react by shining a floodlight back their way - your light will considerably outperform theirs and they'll be blinded.

The earlier generation of laser jammers did merely this - overloaded the police laser gun with a lot more light on the very same wavelength. Nevertheless, this proved irregularly effective - often times it worked well, but sometimes it may well fail. In this business, you've got to be 100% successful or you will be finding cash for a considerable amount of tickets! Police laser gun producers also got a bit wise to the trick and began utilizing 'jam codes' that convey to the officers the fact that gun is being jammed.In reply, laser jammer producers pulled another trick from their sleeve. Overall, the electronics of the police laser gun are extremely sophisticated. This technique of emitting, receiving, and timing the light happens more than a hundred instances per second. That’s correct - per second. The pace at which this occurs is referred to as the pulse rate, and many guns send out light pulses at a rate of 100-140. Certain guns will go up to even 200 or perhaps higher.

Laser jammer suppliers started emitting the jamming light at the exact same pulse rates as the guns themselves! Now, the police laser guns are receiving incredibly bright light, at the same wavelength, and also at exactly the same pulse rate.As they quite simply once stated in the game named Pokemon - it's super effective!

So there you have it - you've now learned how laser jammers operate. It’s helpful information to have and ideally it’s gotten you more interested in laser jammers and laser gun countermeasures!

How Does A Police Laser Gun Get Your Speed
Most of us have already been through it: Sitting, noiselessly fuming, from the driver’s seat of our own car.
