From my understanding, the 5mw limit doesn't necessarily apply when a laser is scanned and has appropriate interlocks. For example the valve lighthouse (VR base station) is classified as class 1, but contains class 3 laser sources.
I think the scanning laser path is more likely to be what you want. Projection-based solutions will probably end up being a lot larger (and more power hungry), as I think you'd need a reasonable amount of quality optics to make anything resembling a sharp line at 1m distance from anything described as a 'small' gadget.
- divan 4y agoThanks for the comment. Scanning laser path is something like LaserCube is offering, right? I talked to them and they warned that it's a class 4 laser and shouldn't be used anywhere accesible to people for safety. So yes, basically what I'm looking at the moment is a way to verify the intuition about if that's even possible. Or what minimum size/power is needed to do that ring. And it's either a lot of DIY that are beyound my skills and time at the moment, or some good simulation software. I'm playing with Blender + LuxRender, but it's still too slow on my M1 and it's basically bruteforcing ideas instead of proper design.
- tomn 4y ago> LaserCube Hmm, that looks like a 2D galvo scanner. I was thinking more like a laser pointer and a mirror attached to a motor. > what I'm looking at the moment is a way to verify the intuition about if that's even possible You just have to build it! It's definitely possible, and the only question I have is the power of laser needed to be visible in your environment for a given circle size, and a simulation will not tell you that.
