Interesting idea, -h.

On the other hand I am not sure what information we would glean that isn't already fairly accurately available in a slanted-edge-derived MTF curve.

I don't know the details about that test, but does it give reliable information about >fs/2?

The edge can be described by an analytic function, so I guess if a good model can be fitted to the samples of such a chart, it might be possible to estimate the PSF denser than what the sensel pitch would suggest in a Nyquistian sense?
