WebRayleigh criteria tells us the condition when the two images of two objects will be resolvable WebThe MTF also relates the diffraction limit to the aberrations in a very clear way. So in order to understand MTF, a short introduciton to diffraction is needed. Diffraction aperture ... According to the Rayleigh criterion, two points are resolved if the central maximum of one point is over the ﬁrst zero of the second.

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 ...
