WebApr 11, 2024 · In Section 2, we discuss a simple, heuristic treatment of the Lau effect, by using a tunable magnification. In Section 3, we formalize the heuristic geometrical optics treatment, by using scalar diffraction in the paraxial regime. In Section 4, we use a grating coded with the Barker sequences, for achieving Lau patterns with narrow peaked profiles. WebThe unique property of having light only in certain orders makes the diffraction grating a key component in many optical systems. Since the angular position of the diffraction spot changes with wavelength (according to the grating equation), a white light source will be split into its spectral components at different angles. This makes gratings ...

WebOptical gratings (also: diffraction gratings) are periodic structures used to diffract light. Optical gratings consist of parallel, line-like structures, where the grating constant is the period of the grating. If coherent light falls on a grating, the light diffracted at the individual grating lines interferes and forms an interference pattern. Web1 day ago · Diffraction Grating Applications.
