I'm trying to figure out the intensity of light in different sections of a 2d airy disk from a point source, but I'm not sure how to calculate it. Does anyone have any good sources?

You need to be able to calculate values of Bessel functions. I've seen online Bessel function calculators... try a Google search for them.

Thanks Jtbell. I actually found that about an hour or so after I posted lol.
I'll look up that Bessel Function calculator, thanks for suggesting it.
