Rayleigh criterion diffraction limit

WebDLA is an acronym for Diffraction Limited Aperture. This aperture value is the result of a mathematical formula that approximates the aperture where diffraction begins to visibly negatively affect image sharpness at the pixel level. Diffraction at the DLA is only barely visible when an image is viewed at full-size (100%, 1 pixel = 1 pixel) on a ... WebThe Rayleigh criterion for resolution postulates that two points are considered resolved if the maxima associated with their diffraction patterns are separated by at least the first root of the function (normalized coordinate x 0 in Fig. 5). In other words, the maximum of one function overlaps with the root of the second function.
