WebNov 26, 2024 · Rayleigh criterion. When a star is observed with a telescope, the light is diffracted or spread apart into an Airy disk. The resolution limit is defined as the minimum angular separation between two stars that can still be perceived as separate by an observer. The angular diameter of the Airy disk is determined by the aperture of the instrument. WebThe Rayleigh criterion for the diffraction limit to resolution states that two images are just resolvable when the center of the diffraction pattern of one is directly over the first minimum of the diffraction pattern of the other. See Figure 2 (b). The first minimum is at an angle of θ = 1.22λ/D θ = 1.22 λ / D, so that two point objects ...

WebSep 24, 2024 · The Rayleigh criterion is therefore not a fundamental physical law and instead a somewhat arbitrarily defined value. This was clearly stated by Rayleigh himself in 1879: 2 This rule is convenient on account of its simplicity; and it is sufficiently accurate in view of the necessary uncertainty as to what exactly is meant by resolution.
