I suspect they are talking about this one here ?

The thing has a size of 19.74mm X 29.91mm.
While this is certainly a way to do it, it is worth to mention that you are essentially doing macro tests.
You can, of course, use several of those to extend "the chart area".
They mention an infinity simulation method for telescope but just from this single sentence I can't draw any conclusions whether this is something that can be generalized.
