Can you illuminate your eyes with a laser? What might happen? Is it dangerous to draw firecrackers? What might happen? Is it dangerous to push a burning can of Sterno under your teacher's desk when they are on the board? What might happen? Is it dangerous to go to school in the United States? Let me answer this. Yes it is! ! You will not learn what should be common sense, and you will never learn the true history of the world and the United States.
Yes, of course, it is dangerous to illuminate aircraft and other life forms or vehicles with a laser pointer. Many gas lasers have been built and designed for more useful applications, such as making 3D holograms that allow you to see objects from all angles, and see its left and right sides, top and bottom.
When the LED starts, its light goes out in all directions. In terms of visual function, in a dark room, place a Christmas light 3 inches away from the eyes and try to do anything. This is a serious disturbance. Note, however, that maintaining an 11-foot position in the cockpit of an aircraft is a challenge. The return lights are not bright enough, usually the brightest things you can see are the running lights on the wingtip, tail, and abdomen-far from the cockpit.
The laser pointer is LASER-optical amplification by stimulated radiation. They are worse than most people because of their poor supervision. Green lasers are particularly dangerous because the process of producing green also produces very high levels of infrared light, which is extremely dangerous to the human eye. By definition, laser is a monochromatic, coherent and non-divergent beam. In simple terms, this means that it is the most concentrated beam of light you can create.
If you irradiate it with a laser pointer to completely cover all the eyes of the fly, it usually stays in place until you touch it—probably invisible. You can often catch live flies this way. When you remove the laser, the fly’s vision seems to return to normal.
It turns out that even a more powerful green laser pointer does not seem to permanently blind the flies. The flies become too hot and leave before the eye is injured (I use 50-150mW 532nm DPSS and 500-1500mW 455nm diode). This makes sense. The compound eye of a fly consists of a large number of very small lens elements, each of which focuses on its own receptor.
