See more Fourier optics is the study of classical optics using Fourier transforms (FTs), 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 See more Light can be described as a waveform propagating through a free space (vacuum) or a material medium (such as air or glass). Mathematically, a real-valued component of a vector field describing a wave is represented by a scalar wave function u that … See more Fourier optics is somewhat different from ordinary ray optics typically used in the analysis and design of focused imaging systems such as cameras, telescopes and microscopes. Ray optics is the very first type of optics that most of us encounter in our lives; it's simple … See more Electrical fields can be represented mathematically in many different ways. In the Huygens–Fresnel or Stratton-Chu viewpoints, the electric field is represented as a superposition … See more The equation (2.1) above may be evaluated asymptotically in the far field (using the stationary phase method) to show that the field at a distant point $${\displaystyle (x,y,z)}$$ is indeed due solely to the plane wave component with the wave vector See more In a high level overview, an optical system consists of three parts; an input plane, and output plane, and a set of components between these … See more Fourier optics is used in the field of optical information processing, the staple of which is the classical 4F processor.

WebIn optics, the Fourier transform can be used to describe the diffraction pattern produced by a plane wave incident on an optical mask with a small aperture [1]. This example uses the fft2 function on an optical mask to compute its diffraction pattern. Create a logical array that defines an optical mask with a small, circular aperture.
