Rayleigh distance
WebJan 3, 2024 · Rayleigh's criterion states that it becomes essentially difficult to resolve two incoherent optical point sources separated by a distance below the width of point spread functions (PSFs), namely, in the subdiffraction limit. Recently, researchers have achieved superresolution for two incoherent point sources with equal strengths, surpassing ... WebFrom there we can define the Rayleigh Range as the distance from the beam waist where the area of the gaussian beam doubles, or in other words, where the diameter of the beam …
