Let's suppose i want to send a message over really big (interplanetary, maybe out of the solar system) distances.
I read the Rayleigh formula, but i also read the a telescope array can give even better angular resolution.
Does that also means, instead of one giant laser focusing mirror, hundreds of smaller lasermirrors in an array even better?
What is the difference between a big mirror, or simply one with really great focal length? Is that only meant to make targeting (manufacture the mirror) easier, or somehow really compresses the beam?
