    I 2mm x 2mm mirror array construction - can you help?

    I’m looking to construct a 500mm x 500mm array of 2mm x 2mm mirrors (i.e. 250 x 250 mini mirrors). Each tiny mirror is at a different angle. The mirror angles are all preset - there is no need for any to move - such that the entire panel can be designed on a CAD package. I am thinking this...

    @Drakkith, thank you so much for that. Yes, that's why I was trying to do this with a small window first. Then I'd scale it up to the much larger window for the final project. @tech99, thanks! I know Pepper's Ghost, but I don't think that would work as I'm wanting the image to appear at (near)...

    I Optics: infinite light source illusion question - can you help?

    Hi. I’m trying to solve an optics problem and really struggling. The problem is best described as follows… Imagine you have a section of a wall that you want to look like a window on a spaceship. So you want to look at this “window” and see through it some “stars” (i.e. pinpoints of light) that...
