Recently I saw two questions pop up that didn't jump out as photography themed: What does "distortion <XX%" mean in lens specs? and How to read a lens spot diagram?. After a response from the poster, it looks like they are on lenses that are used for machine vision. I am unfamiliar with this, but this brings up the discussion point - are questions about lenses uses for industrial applications on topic?
I think we should apply the same rule as for video:
Can I use this information in still photography?
If it's very specific to machine vision — about optics, techniques, or terminology not applicable to still photography? Then it's probably not right for here.
I don't know about theses particular questions, but I'd love to see them answered in a way that relates these technical diagrams to those more typically used in photography. That way, I'd learn something.
My thought process is this:
- If we consider a question like this on topic, would we not be inviting any and all questions about optic and optical devices to be asked and answered here?
- Wouldn't the questions given as examples fit better on a physics or engineering stack exchange site?
If we open up to all optics questions, are we prepared and willing to answer questions about microscopes, telescopes, etc? I only have a general understanding(if that) of machine vision, so I could be way off, but I am leaning towards off topic.
