Rayleigh resolution
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 WebSep 24, 2024 · The Rayleigh Criterion for Microscope Resolution The Point Spread Function & Airy Pattern. When a point emitter (such as a quantum dot) is imaged by a microscope, …

The ability of a lens to resolve detail is usually determined by the quality of the lens, but is ultimately limited by diffraction. Light coming from a point source in the object diffracts through the lens aperture such that it forms a diffraction pattern in the image, which has a central spot and surrounding bright rings, separated by dark nulls; this pattern is known as an Airy pattern, and the central bright lobe as an Airy disk. The angular radius of the Airy disk (measured from the center … http://astronomy.tools/calculators/telescope_capabilities

WebOutils. Les "systèmes de détection acoustique distribuée" (ou DAS pour distributed acoustic sensing) basés sur la diffusion de Rayleigh utilisent des fibres inutilisées de câbles à fibres optiques pour fournir une détection de signaux de contrainte de fréquence acoustique, tout au long de la fibre (d'où le qualificatif de "distribuée" ).
