Dear @marcan42,sorry to disturb but you are my tech. reference :-) and as it seems you are on laser today may i ask you what are your tech idéas concerning this device: https://www.kickstarter.com/projects/1508643250/vvd-an-affordable-real-3d-volumetric-display?ref=discovery&term=Vvd …
Is it diy-doable ? DLP (DMD) based ? Is the "screen" moved thx to galvos ?

I'm assuming it's probably just a polarizing sheet, similar to the material used in sunglasses. I don't think that would be hard to get, it's the DLP that would be more of a challenge.
Why would it be a polarizer? What purpose would that serve? I figured it would just be some translucent film (e.g. the kind of stuff used for rear projection). But yeah, easy to source something that will work. The DLP is the issue. Though it can't be that hard to reverse...

I'm most intrigued by how noisy it will be... I'd expect that persistence of vision like this will require a fairly high (>60Hz) refresh rate, especially given that this can't rely on phosphor emitting light after the break has moved on...

That's a big excursion for what is effectively a large diaphragm...
