The University of Texas at Austin Fourier Optics EE383P 2. far field , Fraunhofer Diffraction Patterns Circular aperture. Or, image of a point source (star) for an optical system with a circular aperture stop. The University of Texas at Austin Fourier Optics EE383P 3. Rayleigh Resolution Limit Two stars well separated (left) Two stars at Rayleigh limit (right). The University of Texas at Austin Fourier Optics EE383P 4. Fresnel Zones Each Fresnel zone boundary is defined by an extra increment of half- wavelength for the distance to an on-axis observation point. The University of Texas at Austin Fourier Optics EE383P 5. Fresnel Diffraction Behind a Circular Aperture 1. Circular aperture viewed on axis (symmetric Fresnel zones).
