You aim it at what? Who has that?

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

Edit: you should note, iPhone already does this for face ID. It's not really that much of a stretch to make it go the other way.
