The purpose of Fourier optics is essentially to calculate and analyze how light propagates e.g. in optical instruments like microscopes, taking into account its wave nature (in contrast to geometrical optics). Both refractive and diffractive optics can be investigated with Fourier optics.

Fourier Optics. Fourier optics methods can be visualized by considering the Fraunhofer diffraction pattern of a single slit. The diffraction process transforms the slit in the object plane to a diffraction pattern in the distant image plane. Based on diffraction theory and the propagation of the light, Fourier optics is a powerful tool allowing the estimation of a visible-range imaging system to transfer the spatial frequency components of an object. The analyses of the imaging systems can thus be performed and the the performance retrieved. For a better understanding of the optical study, we present a short introduction of the Chapter 2 Elements of Fourier Optics or Physical Optics . Peter Eschbach .

A 4f correlator optical system is a system architecture that uses Fourier Optics.In this article, we will explain why we need them and how to design a simple 4f correlator. Diffraction, Fourier Optics and Imaging covers topics central in diffractive optics, multidimensional Fourier methods and most modern analog and digital imaging/image processing techniques. Some algorithms discussed such as information recovery have close connections to other areas such as modern cryptography, super-resolution, lensless imaging View Fourier optics (2).pdf from ECE 5606 at George Washington University. • Fourier optics lecture ECE 5606 Adv. Optics Lab Outline • Motivation – Spatial frequency – Fourier transforming There exists a fractional Fourier-transform relation between the amplitude distributions of light on two spherical surfaces of given radii and separation. The propagation of light can be viewed as a process of continual fractional Fourier transformation. As light propagates, its amplitude distribution evolves through fractional transforms of increasing order. This result allows us to pose the We present an extension of Fourier optics—matrix Fourier optics—for understanding these devices and apply it to the design and realization of metasurface gratings implementing arbitrary, parallel polarization analysis.
