Sorry for the confusion... of course lasers don't detect anything... but
using lasers and receivers that do decode the information carried by the
returning laser light (that is how the range finding lasers and scanning
lasers work)... one would "only" have to build a reciever that could do the
needed calculations carried back by the lasers, and from the calculations,
the correct colours would be generated.
It's not here yet. Maybe it won't ever get here, but that would seriously
surprise me. When I was 8 years old, I made people laugh, by talking about
cooking food with fast radio waves. Ok, I didn't have the whole concept
clear, but this was before any microwave oven had ever been made. And no,
it´s not radio waves, but microwaves... My idea back then was also based on
the "assumption" that if the "fast waves" would hit a target, the molecles
would shake and create heat. Not bad for an 8 year old.
Then there was the wireless transfer of electricity over large distances,
also done with "fast radio waves"... same summer thoughts ... 35 years
later, the first tiny steps have been taken into research in that area.
If I had the whole concept, I would absolutely take out patents and rule the
world :) I only have loose ideas, and many of those have come true over the
years. I am sure that lasers can be used to replace glass lenses. At least
to a certain degree.
