.31 13 The optical Fourier transform configuration. 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.

Let's calculate the Fourier transform of the pulse signal (Section 2.2. 5: Pulse), p(t). P(f)=\int_{-\infty }^{\infty. P(f)=e^{-(j\pi f\triangle.

As an addition to textbooks, it may present some visual help Figure 1: Fourier Transform by a lens. L1 is the collimating lens, L2 is the Fourier transform lens, u and v are normalized coordinates in the transform plane. Here S is the object distance, f is the focal length of the lens, r2 f = x 2 f + y 2 f are coordinates in the focal plane, F(u;v) is the Fourier transform of the object function, u = ¡xf=‚f, and v = ¡yf=‚f. Fourier optics is the study of classical optics using Fourier transforms, in which the waveform being considered is regarded as made up of a combination, or superposition, of plane waves. It has some parallels to the Huygens–Fresnel principle, in which the wavefront is regarded as being made up of a combination of spherical wavefronts whose sum is the wavefront being studied.
