How does laser jammer work?

Even if a gun is unknown, the jammer can still time between a few of the guns pulses, calculate the time window, and attempt to jam the gun by sending pulses in the time window, which the gun should accept.

But since the gun is unknown, the jammer won't be optimized for jamming it, so in some cases a default algorithm could be very effective, while not so effective in other cases.

Thanks for the quick reply :)
Do LED type jammers use a look-up table like diode type?

How important is absolute 90 degrees angle of the sensor heads? Is 89 degrees or 91 degrees acceptable and jam just as affective as the 90 degrees angled sensors?

When car is moving through uneven pavements, I would think even perfectly installed sensor will be off axis thus not being at true 90 degrees angle.

The energy coming from the heads is similar to light from a flashlight. If someone shines a flashlight directly in your face, it appears very bright. If they aim it a few degrees over your head, it will still be bright, just not as bright.

I'm not certain of the angle effectiveness; I'm sure it depends on the emitter. I've had several jams of guns above me on overpasses, so these were shots that were not straight on to begin with, but as I got closer, the LEO was likely able to determine my speed as the angle increased.

I think the main reason to mount them as close to 90 degrees is to cover the spread - those overpass shots and shots when you cover over a hill and the gun is below you.

I am trying to see the operational difference between LED types and diode types...

The only core difference between LED and LD jammers would be the driving circuit for the LEDs / LD

I'd doubt it, then if it's true, how can you explain the Blinder J15 jamming the TS?

Not sure what you're asking here. The Blinder barely jams the TruSpeed at all.
