laser pointers

ouch

There is 904nm light made by the sun all the time. The RD needs it to be pulsed, that's why Laser Atlanta "stealth" mode usually doesn't trip them since it's looking for more pulses.

Mind you my mid 1990's Uniden all the time alerted to the sun

Many lights actually are pulsed. Anything running on AC power is... that's why if you look at a flourescent light, it's flashing 60x per second, and it's annoying. An incandescent is doing the same, but because it is "hot" it still emits light in the "off" period. Neon lights are much the s

Laser pointers are the wrong wavelength (visible red, LIDAR is 904nm infrared), and most laser pointers aren't pulsed, which is something else the RD looks for.

Totally disagree on the pointers not being pulsed!!! Most actually are pulsed, especially the cheap ones!! it is hard to find a Constant laser pointer. (fun experiments with them, especially when they are overdriven on purpose)

How to test if your pointer is pulsed: dark room, with the laser on, move the beam very rapidly in a circle at a point on the floor or wall about 10 feet away, if it is pulsed, you will see a dashed line drawn. If it is a constant, you will see a solid line.


As for the wavelenght being wrong, you are correct. Laser pointers are about 400-540 NM, where lidar is 890-950 NM, with 904 & 905 being the most common for USA made guns.

ok so I had a memory lapse............CHevy IS GM..............and im not too big on electrical stuff, so I didnt know that little bit
