Simultaneous display of all the Fresnel diffraction patterns of one-dimensional apertures
نویسندگان
چکیده
An optical setup is implemented for observation and analysis of diffraction phenomena. The device provides a two-dimensional ordered continuous display of all the diffraction patterns of any one-dimensional signal. This result allows a direct comparison between the observed light intensity and the prediction of diffraction theory, both in the near-field and the far-field regions. The arrangement is built with conventional laboratory optical components plus a single ophthalmic progressive lens. Experimental results for typical diffracting apertures are shown. © 2001 American

Fresnel diffraction and fractal patterns from polygonal apertures.
Two compact analytical descriptions of Fresnel diffraction patterns from polygonal apertures under uniform illumination are detailed. In particular, a simple expression for the diffracted field from constituent edges is derived. These results have fundamental importance as well as specific applications, and they promise new physical insights into diffraction-related phenomena. The usefulness of...
متن کاملAlgorithms for Fresnel Diffraction at Rectangular and Circular Apertures
This paper summarizes the theory of Fresnel diffraction by plane rectangular and circular apertures with a view toward numerical computations. Approximations found in the earlier literature, and now obsolete, have been eliminated and replaced by algorithms suitable for use on a personal computer.
متن کاملFresnel Diffraction.nb
In this section we will look at the Fresnel diffraction for both circular apertures and rectangular apertures. To help our physical understanding we will begin our discussion by describing Fresnel zones. In the study of Fresnel diffraction it is convenient to divide the aperture into regions called Fresnel zones. Figure 1 shows a point source, S, illuminating an aperture a distance z 1 away. Th...

In this paper Fresnel diffraction of light from 1-dimensional and circular steps in reflection and transmission modes is theoretically and experimentally studied. The study shows that the diffraction pattern from each side of a step resembles the diffraction pattern from a semi infinite obstacle, but the visibility of fringes is a sensitive periodic function of the step height and the inciden...
متن کاملGeneralized Jinc functions and their application to focusing and diffraction of circular apertures.
A family of generalized Jinc functions is defined and analyzed. The zero-order one is just the traditional Jinc function. In terms of these functions, series-form expressions are presented for the Fresnel diffraction of a circular aperture illuminated by converging spherical waves or plane waves. The leading term is nothing but the Airy formula for the Fraunhofer diffraction of circular apertur...
