From two Fresnel zone calcu-lations, one ﬁnds an ideal Fourier transform in plane III for the input EI(x;y).32 14 The basis of diffraction-pattern-sampling for pattern recognition in optical- Learn Fourier and diffractive optics through examples and computer simulation. This book presents current theories of diffraction, imaging, and related topics based on Fourier analysis and synthesis techniques, which are essential for understanding, analyzing, and synthesizing modern imaging, optical communications and networking, and micro/nano systems. (2) Example Application to Diffraction from a Slit (mathematical and optical) Some really cool 'fast Fourier transform' or FFT examples (and credit for next few By placing an optical aperture in a Fourier plane, one can effectively modulate the spatial frequency spectrum. For example, with a circular aperture centered on Here is presented a simple example, where a plane wave is propagated using the result shown in the manuscript 3.
