WebIn that case, the angular resolution of an optical system can be estimated (from the diameter of the aperture and the wavelength of the light) by the Rayleigh criterion defined by Lord Rayleigh: Two point sources are regarded as just resolved when the principal diffraction maximum of one image coincides with the first minimum of the other.If the … WebThis calculator is based on the Rayleigh criterion, which states that the Airy disks should be at least one radius apart. The radius of an Airy disk is the distance from the center to the first zero. Mathematically, the minimum angle that can be resolved based on this criterion is. \alpha = \dfrac {1.22 \lambda} {D} α = D1.22λ.

WebRayleigh's Criterion is usually applied to circular apertures, where the criterion for resolution is when the center of one Airy disk pattern falls on the first minimum of the Airy disk pattern of the second source. The angular separation θ is then. θ = ( 1.22 λ ) / D. where λ is the wavelength of light, and D the aperture diameter.
