Making a digital camera is a project that appears easy enough, but it’s one whose complexity increases depending on the level to which a designer is prepared to go. At the simplest a Raspberr…
It would be super cheap to make a laser difraction grid. You could map the lense deformation because you know the lines on the grid are straight. This would be solely for mapping the properties of the lens / mount and how to handle defamation profiles. Once you dial in the lens you probably wouldn’t need to run it again assuming it can id the lens when you mount it.
I would say you could use red green and blue lasers and look at convergence, But I’m not sure in any decent hardware that that would actually be off
They have an incredibly high degree of accuracy. It’s the same thing iPhones are using for face ID. And if you needed it to be easier it doesn’t have to be straight lines as long as it’s dots in known locations

“It would be” so you haven’t done this but speak confidently about it being cheap and accessible?
You can purchase laser pointers with grid diffraction grating right now with zero effort to DIY.
You can purchase house decoration style diffraction gratings which are a larger format but are intensely bright. They are however less portable.
You can follow a thought emporiums instructions on how to create diffraction gratings, which includes the software and the process,
And yes, I already own a 300 milliwatt laser with a diffraction pattern that would work for this.
And these things produce actually perpendicular lines?
