WebAccording to the Rayleigh criterion, it is just possible to distinguish the image formed by two points when the center of one Airy disk overlaps with the first-order dark ring of another Airy disk. At this time, the distance between the center of the two Airy patterns is equal to the radius of the Airy disk. WebThe Rayleigh criterion is named after English physicist John William Strutt, 3 rd Baron Rayleigh (1842-1919) who investigated the image formation of telescopes and microscopes in the late 19 th century. Rayleigh defined the resolution limit as the separation where the central maximum of the Airy pattern of one point emitter is directly ...
