If you really use a powerful laser, you have an aid to aim directly at the camera, if the remote pilot uses trans-horizon/first-person vision, then he will be forced to use the map to navigate and eventually go home. It will be very difficult. Compared with manned aircraft, green laser pointer are much more harmful to drones.
If extremely high-power terrestrial lasers can liquefy a 100-meter-high asteroid before it comes into contact with the Earth’s atmosphere, will it reduce the damage to the ground? In fact, this makes the problem bigger, not smaller.
The energy as heat compresses upon impact, leaving behind a larger shock wave, because the sublimated rock and the like will now have a higher temperature, resulting in a larger pressure wave. More prosperity, not less prosperity.
Why does my wireless mouse work, but the red laser part below does not work, and I don’t see it light up, why? Is the laser broken, but the mouse can still be used?
Some of them use invisible IR. Some of them still use visible red, but the level is high enough to reliably illuminate the surface on which it is used, but too low to be easily seen.
At a few milliamps, this LED consumes most of the battery power of the wireless optical mouse, so manufacturers must design as efficient as possible. It works, I will let it pass. The behavior of the laser pointer is no different from any other ultrasound-like behavior. They all follow the rules of wave mathematics.
