Rayleigh criterion for circular apertures
WebLight from different parts of the circular aperture interferes constructively and destructively. The effect is most noticeable when the aperture is small, but the effect is there for large apertures, too. Figure 1. (a) Monochromatic light passed through a small circular aperture produces this diffraction pattern. http://pressbooks-dev.oer.hawaii.edu/collegephysics/chapter/27-6-limits-of-resolution-the-rayleigh-criterion/

WebLLO Explain Fraunhofer diffraction at a circular aperture and define Rayleigh’s criterion for resolution. Engineering Physics. Lecture Summary – Key Takeaways. The diffraction due to a circular aperture is similar to the diffraction due to a single slit. The waves travelling some distance to reach Po have no path difference. 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 ...
