The basic text is supplemented by over 170 files in Maple, MathCad, Mathematica, and MATLAB (many of which are in the text, each suggesting programs to solve a particular problem, and each linked to a topic in or application of optics. • Goodman, Introduction to Fourier Optics, W. H. Freeman ì ì ð. this comprehensive textbook is the standard reference when it comes to Fourier optics. these two papers discuss the relationship between Fourier optics, ray optics and lightfields, and the Fourier analysis is a ubiquitous tool that has found application to diverse areas of physics and engineering. Goodman focuses on applications in optics, and in particular with applications to diffraction, imaging, optical information processing, holography, and optical communications.

I was looking at the derivations behind the Fourier transform and the fact that the Fourier transform of the aperture function is the diffraction pattern in Fraunhofer diffraction.

Fourier optics G For example, for a single lens of diameter D, the point spread function is the “Jinc,” function or the Besssel function analogy of the “Sinc” function. The psf(u,v) = Fourier Optics• Fourier Optics is the application of linear shift invariant system theory to optical systems• The plane wave in an optical system is represented by the multivariate complex exponential just like the sine wave in an LTI system is represented by the j t single variable e• Just like an electrical signal can be represented as summation of sine waves, an optical image can be represented as a summation of plane waves – Angular Plane Wave Spectrum Pg. 11 2018-08-02 · Summary of Fourier Optics 1. Plane waves propagate in straight lines 2. Gratings of spatial frequency diffract in a particular direction 3. Spatial filtering: Add a mask at the Fourier plane to block unwanted Fourier components of f (x, y). Transfer function of the mask for the Fourier components: H(νx ,νy ) = p(λfνx ,λfνy) (4.4-4) Output: G(νx ,νy ) = H(νx ,νy )F(νx ,νy) Example: (a) Low-pass filter ( , ) 1 for 2, : cutoff frequency s 2 y 2 Several examples are shown at 532 nm, both indoors and outdoors.
