Hi, i dont really know much about this and thought someone here might be able to help, im trying to design a periscope to project onto a wall inside a building (with no artificial projection so using no electricity) it needs to be passive so that it can project the movement of the sky over the course of a day.
heres a brief mock up its litertally taking a periscope and reflecting the image onto a glazed wall that the viewer would be on the other side of, but im not sure how this would work in terms of using a lens to magnify the image onto the wall (hence keeping the distance between the wall and mirror to a minimum) i have attached a very crude image any comments/help would be really useful including how this would work in 3d if i wanted to project across a whole wall- would the periscope then need to span the entire distance?
thanks in advance
(any suggestions are seriously welcome as im a bit lost on this one)
