Help me, Hacker-News; you're my only hope

Q. Does "scanning" have the same meaning as in "raster scanning", where you cover the area (volume) in a set pattern? If so, I would have thought a vector approach would work better here...

Q. What is a "motor orbit"?

"The linear motor system enables the position of the laser focal point to be varied by high-speed scanning of a lens set on the motor orbit. Incorporation of this system makes the image scanning in the direction of the z-axis possible. For scanning in the x and y axis directions, conventional galvanometric mirrors are used."

It took me a while to realize that it's not the intersection of two lasers, but the focal length of one laser. I didn't realize you could do that with coherent light, but of course you can.



I kept thinking of that scene in Star Wars too!

Instead of a raster or vector approach how about an array of lasers all with fixed focal lengths that project into a predetermined 3D viewing space? Kind of like a 3D LCD setup. Tbh they've probably already thought of these ideas. As Obi-Wan says: "Patience".


I think that's a good idea, but wow too expensive! Why not have a laser for each voxel in 1000x1000x1000 space? :-) Seriously, that may be the kind of breakthrough needed for this research to be commercially viable.
