Great question. Many of the laser vortexes that people build have a tilted mirror mounted at the axis of rotation with a stationary laser directed to the mirror. This creates a laser sheet cone. However, with this design, all laser sheets will appear to originate from a single origin. If the lasers are positioned off axis like with the design I built, you are able to create converging laser sheets, like the hourglass shape shown above. You are right though, for the easiest laser vortex build, all you need is a single mirror mounted to something that spins.
cool it looks like excursion funnel from portal 2
Amazing work! Thanks for continuing to do such projects that give concreteness to abstract concepts. Very informative video.
Tremendous work!
Nicely done, thanks for sharing.
Wow, great project!
Thank you for checking it out!
nice socks ;-) (and awesome project)
Haha, thanks!
I'm curious... Why spin the lasers? Why not just deflect the beams with spinning mirrors?
