WebFeb 20, 2024 · You've asked about the criterion, not the use of the 1.22 equation. From hyperphysics (and pretty much everywhere else): The Rayleigh criterion is the generally accepted criterion for the minimum resolvable detail - the imaging process is said to be diffraction-limited when the first diffraction minimum of the image of one source point … WebWhen two adjacent Airy patterns reach the Rayleigh criterion, the resolution equation reduces to: D = r = 0.61λ/NA. In cases where two adjacent Airy patterns become closer to each other than in the Rayleigh criterion, the separation is known as the Sparrow limit, which is given by the equation: D = 0.47λ/NA

WebThe Rayleigh Criterion can be mathematically described by considering angular separation and single-slit diffraction. Angular separation can be calculated using the equation: … 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. dgft functionsWebThe Rayleigh criterion specifies the minimum separation between two light sources that may be resolved into distinct objects..
