Can Police Use Laser Guns From Inside Their Car?

Automotive

You might have seen it before – you are traveling along the interstate and you see a police officer in his car shooting LIDAR out of their driver’s side window. Perhaps you’ve even spotted an officer targeting through his windshield or via the side-view mirror?

The question is: can law enforcement officials employ LIDAR from inside their car or truck? In short, Yes!

Police laser, officially named LIDAR is an acronym for LIght Detection And Ranging. Among the laser jammer online community, ‘laser’ can be the more frequently used term, but LIDAR is equally acceptable. Police laser guns may look complicated and daunting, though with a bit basic familiarity with math along with an example or two, anyone can understand how it performs strategies to, then defend against it.

Overall, police laser (LIDAR) guns calculate speed by using infrared light to measure distance a few hundred times (in just a few seconds). The genius of police laser guns, compared to radar guns, are how the laser beam concentrates onto an extremely tiny area that it can only focus on one automobile at a time. Officers would like to be in a position to locate one exact vehicle, and the laser gun’s little beam enables them to do so. Light beams broaden when they travel; they may start as small as a pin as soon as they leave the laser gun. Even so, after 1000 ft, the beam is just about six ft wide, still small enough to focus on only one automobile.

Many officers running speed enforcement with LIDAR choose to sit perpendicular towards the road and shoot at oncoming traffic from their driver’s side window. Why would they do that from the inside of their car? You can find 3 major reasons:

1. Laser guns are heavy!

Although they might not look like it, a good number of laser guns have state-of-the-art and heavy innards, which can put pressure on an officer’s hands and arm if he or she is shooting for an lengthy time. For this reason, some officers will in addition utilize a tripod or rest the LIDAR unit on top of their car and target vehicles from behind the car.

2. LIDAR guns have to be steady

Most people have certainly not used police laser in the past, therefore they do not understand how tricky it may be to truly concentrate on a car coming from a sizeable distance away. To acquire a speed reading, the officer needs to maintain your car or truck targeted for about a second and keep from ‘sweeping’ sideways. Sweeping or abrupt movements could very well give an incorrect speed readout.

3. They are ready to go

At the time a police officer gets a speed readout, he needs to then go chase the speeder! If he’s already seated in the car, he’ll be able to just put his car into drive and turn on their red and blue lights. If he’s standing outside of the vehicle, he had to open up his car door, get inside, and then pull out, leading to lost time and quite possibly a missed ticketing prospect.

As previously mentioned, some police will shoot the laser gun via their windshield and even reflect it off of their rear-view mirror at oncoming cars. This actually will generate a speed readout, but these methods will probably decrease the device’s functionality and quite a few LIDAR gun companies usually do not endorse these methods.
