Possible or not?

[arksys]

Hi All,
I've posted this before but thought it might be an idea to try again. Would it be possible to project a 1 metre grid onto a concrete floor covering an area 100 metres by 80 metres with a maximum tolerance of 5mm?

Many thanks in advance.

Possible. Yes.

Easily done. No.

Ridiculously expensive. BIG yes. Especially with low tolerance, and I assume some level of portability, and ability to reprogam.

This might be a question better suited to photonlexicon than laser pointer forums, as it would be a very advanced project. This is more of a beginner - entry level - hobbyist forum.

Edit: A custom diffraction grating, couples with a labbie, if suspended from a specific height, could work. Of course getting that to work with a 5mm tolerance.... good luck.
