I started with improving the optical layout of the Hexastorm. Luckily, there is a company from Colombia, cihologramas.com, who made an open-source optical package for optics and also
provided some instructions on how to integrate this into FreeCAD. You can seen the result below.
I will explain the whole simulation in a different video.
They report a resolution of 25400 dpi, which is 25.4 (mm)/ 25400 = 1 micron.
Production speed is 55 cm^2 per hour, i.e. a square sided 7.41 cm.
These are 74100 lanes with a length of 7.41 cm, which is 1.54 m/s .
Most likely, they use a galvo scanner. It might be done much faster with a prism as well, but I would have to recheck the whole design. I will outline in the next video, how you can make a design, in the first place.
Here is one of their holograms;
