How to build an MTF of various aberrations?

Dear Colleagues,

I am doing a study (just out of curiosity really) on the impact of turbulence on telescopes of various sizes and quality. I am stuck - can't find any info how to build a MTF curves of various aberrations resulting from, say, central obstruction, surface roughness or spherical aberration. Google outputs lots of basic info but no formulas. It seems that such applications like Aberrator do the job but authors do not describe the methodology applied.

I would appreciate your help very much!
