LIDAR Working?

Stolen from the Johnny Law Chronicles:

So what's up with the LIDAR devices in every district? Are they pulling their weight? Or is it another pointless mission keeping cars down and contributing to the near constant backlog in the busy zones?

Retired State Police Sergeant here...
I had a LIDAR unit for a few years which I would assign to my squad of troopers during speed details and such. We found that they weren't as practical as radar guns. We sometimes had problems with firing the laser beam thru the windows in the squad cars. Occasionally errors would appear or the range was greatly reduced. The best result was when the operator was outside of the car with a clear line of sight, but who wants to stand outside all day peering thru the reticle. We did find them helpful at fatal crash scenes though, especially the long ones that could be a few hundred feet on the interstate. Instead of using our 100' steel tapes to measure the scene, the LIDAR was used in distance measuring mode and the job was done quickly and safely. We didn't even have to shut down lanes as we could stand on the shoulder and measure to the center guard rail even with traffic whizzing by. But for ease of use, and being able to bounce the beams off the outside mirrors if necessary, give me a good hand held radar any day.
Stay safe CPD.

By "pulling their weight" do you mean are they generating revenue for the city?
Most LIDAR trained officers are traffic cars. Most traffic cars are constantly runnig from job to job.
Now the bosses are demanding all LIDAR trained officers to report (every day) how many tickets they issued using the LIDAR.

LIDAR is a nice tool to have. None the less, they are wrong to pressure us to show activity with the lidar, when we are usually occupied with paper for accidents.
Being able to use the lidar when there are no jobs pending is great.
Being FORCED to use the lidar sucks!!!

Stupid question of the day: Is Lidar the same thing as Radar?

BTW, only State Police are allowed to run radar in Pennsylvania. How does it work in Illinois? Can any LEO use it, or is it a State Police thing there too?

Hey...I think it's working. I mean, the cars I see driving on the street now do 50 rather than 70.

Man, all the late rapids (1800 cars) in 025 all hide on bogus missions. Their Sgt. keeps it that way. If they make an arrest they all go down on it. (6 cars on 1 head) They are just plain USELESS!

If I had lidar or radar in my squad I would use it as a coffee cup holder or a page turner for my daily paper! Take all the new toys and make use of them for relaxation! maybe the clout white shirts could use them and show their slaveowners who promoted these dickheads how great the new things are!

Years back as a recruit I was speeding down a back road trying to find a back road to Shore's Gallery, I passed a Linclonwood squard car head on. To my surprise he flipped a u and came after me! I pulled over told him the mistake I made (joining CPD, not speeding) and he let me go. I had to ask. How did you get me speeding? He told me LPD has dash mounted radar that he can just flip on and shoot anyone in any direction!

Wow, i said.

Hey 6/24/07 07:40:00 sounds like you are jealous and want to be on a late rapid. I am sure you hide in your own way like posting some nonsense hiding behind your anonymous mask. You are a coward ripping someone and not identifying yourself.

i am sure yo have less than 5 years on the job and think you are the best copper there ever was. You are one of those 3 or 4 oclock pussies.

Just go hide somewhere. Its obvious you dont listen very well to the radio to make an observation like the one you posted.

You are a big pussy , probably live at home with mom and dad and have a drinking problem. Go away coward and get the counselling you need for the abuse you suffered at the hands of your parents.

Coward...Coward

As one of the CPD LIDAR instructors, here is a functional description of how LIDAR works...first, LIDAR stands for; light detection and ranging. When the trigger is pulled on the officer's laser gun, hundreds of invisible infrared laser light pulses per second are sent out of the unit and a timer is started, and when the energy of a laser pulse is reflected from the target and received back to the unit, the timer is stopped. From the elapsed time taken for the laser pulse to strike and return from the target, the distance to the object
is calculated with the known speed of of light (282,0000 ft. per second) through the atmosphere.
To make this story shorter, this speed determination is then displayed to the operator.
The target vehicle's speed and distance from you are displayed on the device in a matter of 2 seconds. (we have picked off cars at 2,000 feet away on a long stretch of road)

This device is great for us. It's carried in a small case, whereas RADAR must be set up in a car.

The LIDAR guys is 100% pinpoint accurate on the vehicle target you select. For those of you who haven't heard, our beat officers have been picking speeders off at 80 - 105 mph in the 16th.

After writing quality movers like these, you won't be sitting at a stop any time soon. Support the officers on your watch for writing movers like these. Takes the heat off of you with the W.C.

On a side note; after writing a ticket for speeding, I asked why his laser/radar detector didn't save him. Answer was that by the time it went off, officer you already had your blue lights on.

If you want to learn more, sign up for my class when it comes around again at the Academy. I would love to have you there. ml

According to GOOGLE, "LIDAR" is an acronym for "LIght Detection And Ranging" or laser radar.

In 010, our LIDAR guys are doing a great job. In the past, we had the yuppie jags going to and from the suburbs flying down Ogden, not giving a rat's ass that they were showing major disrespect by flying right past the station. When our guys got the LIDAR, everyone agreed that the best place to sit would be right in front of the station. Sure 'nuff, they parked on Ogden with the rest of the blue and whites, and it instantly became the fishing hole. The average speeder gets a ticket for 50 in a 30. We are finally sending a signal to the suburbanites that you can't come into the city and drive like an idiot. They drive that way because such driving isn't tolerated where they live. We should have done this years ago.

HA ha ha...I'd love to see how many of those 80 mph dickheads are coppers! Ever been on Devon around 0030ish? Nothing but cars with FOP shit plastered all over them passing cars at mach 5! Apparently some of you guys never learned that your star won't help you much when you slam into something at 80 mph or above.

How about driving around the District and finding some bad guy to pull over instead of the regular Joe. How about taking a little time out of your busy day to be the Police. I cannot go a City block without seeing some guy that needs a stop, and his bad driving is your probable cause! If you did not catch the big one, write the offender his tickets and/or take his car. They hate it when you mess with the ride.

This seems pretty slow, from what I've read-

The speed of light is 186,000 miles per second or 299,792,458 meters per second or the time it takes for the light to turn green before the guy behind you starts honking.

The speed of light is 186,000 miles per second in a vacuum. It is slower when it has to cut through all gases that make up our atmosphere.

SINCE THE EYE IS ACTIVATED BY LIGHT, IF ONE WERE TRAVELING AT THE SPEED OF LIGHT, WOULD YOU HAVE TO LOOK BEHIND YOU TO SEE WHERE YOU ARE GOING??

Not THAT slow, Chris-

Thanks for trying- at the speed he was trying purport, it would be closer to the speed of sound. Maybe he misplaced a comma or decimal point.
282,0000 ft. per second?

The speed of sound is 761 miles per hour, or @ 1100 feet per second.

Asshat, I see nothing wrong with hauling ass through the woods on the way home from work. Blowing lights is a no-no, but speeding is ok with me. Are you a civilian going 60 that is mad cause the coppers passed you up? Nobody obeys traffic laws anymore, why should we? When I started out everybody wrote at least one shitbird a tour a hazardous mover...Now the college boys are lucky if they write one a week.
