When I shine a laser pointer at something, the point looks like it is made of a bunch of tiny dots, how is the laser diode different from a normal LED?
In: Technology
No one should do this: it looks the same if you stare into the beam of a laser pointer.
It also looks the same if you use a DSLR camera.
It’s fascinating.
If you stare into the beam of a laser at least put a lens in front of the laser so it gets spread out to the point where it is a very weak flashlight.
