Resolution depends on the distance between two distinguishable radiating points. The sections below describe the theoretical estimates of resolution, but the real values may differ. The results below are based on mathematical models of Airy discs, which assumes an adequate level of contrast. In low-contrast systems, the resolution may be much lower than predicted by the theory outlined below. Real optical systems are complex, and practical difficulties often increase the di… WebNov 13, 2015 · When two adjacent Airy patterns reach the Rayleigh criterion, the resolution equation reduces to: D = r = 0.61l/NA.
