WebOct 28, 2024 · The central Airy disk is measured at the first minimum while the FWHM is at 50% of the maximum (as in Full Width Half Maximum). In fact, if you were imaging from outer space with perfect optics and camera the FWHM could be one half the size of the Airy disk (if you were capturing with sufficient image scale). WebAiry disk. An Airy disk is the central bright circular region of the pattern produced by light diffracted when passing through a small circular aperture. The central disk is surrounded by less intense concentric rings, so light intensity takes local maxima and mimina while it decreases away from the center. The size of an Airy disk depends on ...

WebThe Airy Disk and Lateral Resolution. ...
