WebJan 18, 2024 · I'm trying to follow along with the calculation of Fresnel diffraction presented in Siegman's Lasers (1986), page 660. It follows the angular propagation of plane waves in the paraxial approximation. I've gathered that calculating the diffraction pattern formed by an illuminated planar aperture on some other parallel plane is a 3-step process: WebApr 11, 2024 · First, I want to make sure I am understanding everything right: for optical Fourier transform I would put a masking filter (diffraction grating in my case) in the focal plane (which I would have to do a calculation to find where it is located depending on the lens) and it would filter/modify the image.

"A diffraction grating is an optical component with a regular pattern. The form of the light diffracted by a grating depends on the structure of the elements and the number of elements present, but all gratings have intensity maxima at angles θ m which are given by the grating equation See more Diffraction is defined as the interference or bending of waves around the corners of an obstacle or through an aperture into the region of geometrical shadow of the obstacle/aperture. The diffracting object or aperture … See more In classical physics diffraction arises because of the way in which waves propagate; this is described by the Huygens–Fresnel principle See more Several qualitative observations can be made of diffraction in general: • The angular spacing of the features in the diffraction pattern is … See more Diffraction from a three-dimensional periodic structure such as atoms in a crystal is called Bragg diffraction. It is similar to what occurs when waves are scattered from a diffraction grating. Bragg diffraction is a consequence of interference … See more The effects of diffraction of light were first carefully observed and characterized by Francesco Maria Grimaldi, who also coined the term diffraction, from the Latin diffringere, 'to break into pieces', referring to light breaking up into different directions. The … See more The effects of diffraction are often seen in everyday life. The most striking examples of diffraction are those that involve light; for example, the closely spaced tracks on a CD or DVD act as a See more According to quantum theory every particle exhibits wave properties. In particular, massive particles can interfere with themselves and therefore diffract. Diffraction of electrons and neutrons stood as one of the powerful arguments in favor of quantum … See more " - Optics diffraction
