Diffraction patterns of simple apertures

WebThe far-field diffraction pattern of semicircular apertures is described. A general expression is given for the amplitude that is valid over the entire image plane and that reduces to Bessel and Struve functions on the axes. A simple approximation is also given that is valid for all angles at large distances from the origin. WebBegin by working on the ‘simple’ problem of light incident upon an infinitely narrow slit. Then, move to modeling the diffraction from a slit with a finite width. Finally, modify the program to determine diffraction from an edge. For the edge diffraction problem, place a line source, 632 nm, 10 cm behind a slit.
