Good luck on your kickstarter. Hope you guys achieve your goals and ship this amazing tech!

I tried searching for the term "hogel size" I assume it is somewhat equivalent to resolution. Can you expand on it and tell us what are the limiting factors around resolution and how it can be improved in the future?

I am now curious how commercial sticker size holograms are printed.

Thanks! The hogel size is physically determined by things like the aperture size (in our case 1x1mm to start, with a stretch goal for 0.5x0.5mm), but also laser power, and just how long it takes to print each hogel and as a result the full hologram. Double the resolution is 4X the number of hogels.
