Rayleigh criterion for circular apertures
WebJul 13, 2024 · Rayleigh criterion: angular or spatial resolution? The Rayleigh criterion sets the fundamental limit for what features an optical system can resolve. Formally, the criterion is defined for some wavelength λ in the case of a uniformly-illuminated aperture (consider one that is circular) of diameter d. An airy disk is formed in the far field (or ... WebThe Rayleigh criterion stated in Equation 4.5, θ = 1.22 λ / D θ = 1.22 λ / D, gives the smallest possible angle θ θ between point sources, or the best obtainable resolution. Once this …

WebNov 13, 2015 · This figure plots the ratio of the numerical apertures of the condenser and objective versus the minimum resolved distance between Airy patterns (Rayleigh criterion) in units of wavelength divided by the objective aperture. When two adjacent Airy patterns reach the Rayleigh criterion, the resolution equation reduces to: D = r = 0.61l/NA
WebThe Rayleigh criterion is named after English physicist John William Strutt, 3 rd Baron Rayleigh (1842-1919) who investigated the image formation of telescopes and microscopes in the late 19 th century.
