Rayleigh criterion for resolution
http://web.mit.edu/2.710/Fall06/2.710-wk12-b-sl.pdf 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 10.26 (b)). The first minimum is at an angle of size 12 {θ=1 "." "22"λ/D} {} so that two point ...

WebAccording to the Rayleigh criterion, it is just possible to distinguish the image formed by two points when the center of one Airy disk overlaps with the first-order dark ring of another Airy disk. At this time, the distance between the center of the two Airy patterns is equal to the radius of the Airy disk. 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

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 = 0.47l/NA WebFor a point source radiating light at a wavelength of 510 nm and a microscope objective with a numerical aperture (NA) value of 1.4, the value of r from the Rayleigh equation will be 222 nm. The rest of this tutorial will assume the Rayleigh criterion as the standard definition of the resolution limit.
WebThe Rayleigh criterion is a commonly used criterion for determining the resolution limit of optical systems, such as telescopes, microscopes, and cameras. The criterion states that two-point sources can be resolved if the center of the diffraction pattern of one source falls on the first minimum of the diffraction pattern of the other source.
The imaging system's resolution can be limited either by aberration or by diffraction causing blurring of the image. These two phenomena have different origins and are unrelated. Aberrations can be explained by geometrical optics and can in principle be solved by increasing the optical quality of the system.
