... Note that as the aperture size a increases, the PSF becomes narrower. This allows objects to be imaged with higher resolution, and is (part of) the reason for telescopes having such a large diameter. (They also have a large aperture to capture a larger portion of the incoming light.) Synthetic apert ...

F-number
In optics, the f-number (sometimes called focal ratio, f-ratio, f-stop, or relative aperture) of an optical system is the ratio of the lens's focal length to the diameter of the entrance pupil. It is a dimensionless number that is a quantitative measure of lens speed, and an important concept in photography. The number is commonly notated using a hooked f, i.e. f/N, where N is the f-number.
