Rayleigh criterion for circular apertures
WebCircular Aperture Diffraction. For monochromatic light of wavelength λ = nm. incident upon a circular aperture of diameter d = micrometers, d = x 10^ m, and projected on a screen at distance D = m, the displacement from the centerline on the screen is given by the relationship. Displacement y = Screen distance D*m value* wavelength / aperture ... Webof the aperture, and wavelength, λ, of the incident light. Diffraction by a circular aperture is similar to single-slit diffraction. But note the difference: Image plane 0 0 I I0 θ θ o θ D Image plane Point object a λ Slit θ 0≈ 0 1.22 D λ Circular θ ≈ aperture The “Airy disk”. The central lobe contains 84% of power.

WebFeb 18, 2024 · Background. The Rayleigh criterion of imaging resolution says that two incoherent point sources are barely resolved by a diffraction-limited system with a circular aperture where the center of the Airy intensity pattern generated by one point source falls exactly on the first zero of the Airy pattern generated by the second. WebFigure 27.26 (a) Graph of intensity of the diffraction pattern for a circular aperture. Note that, similar to a single slit, the central maximum is wider and brighter than those to the sides. (b) Two point objects produce overlapping diffraction patterns. Shown here is the Rayleigh criterion for being just resolvable.

NA obj is the NA of the objective. NAcond is the NA of the condenser. The value ‘1.22’ is a constant. This is derived from Rayleigh’s work on Bessel Functions.
