Hello.
Pardon my ignorance, but you are the guys who can really help me with your advice.
I wonder, if the following idea will work at all:
I would like to assemble a matrix of 8 x 8 5 mW lasers mounted about 1 inch apart in a grid fashion. At any particular time, only certain laser pointers will be powered. Effectively, I would like to project the letters onto a low cloud or a distant building. For example, when letter "A" is projected, it may require about 15 laser pointers to display it.
My questions are: will I be able to see the outlines of the letters at the distance of several thousands feet? What would be the size of the projected letter (at 2,000 - 3,000 ft distance), if the distance between the first row of pointers and last row of pointers is about 8 in.? Or, by using 5 mW green lasers, I will not be able to achieve what I want it more powerfull & expensive lasers will be required?
Maybe someone has already done somehting similar?
Sincerely,
sadcom
