WebAn example is the thin, flat, BAD Panel by RPG (a 2D binary amplitude diffuser, or binary amplitude diffsorber ). If you overlay the diffusion and absorption coefficient charts for the BAD Panel you will see a combination of diffusion and absorption between 1-2 kHz, and pure absorption below 1 kHz. http://teaching19-20.eng.cam.ac.uk/system/files/P2B2013QB011.pdf isa hep fr

WebDec 15, 2016 · Since we intend to modify the amplitude binary grating as well as the phase profile of the wave-fronts to create POV, a mean of create a binary computer-generated hologram that represents the amplitude grating, this can be realized through Lee method [21] in which the normalized transmittance of the amplitude pattern can be … WebDec 1, 2024 · Generation of the trapezoidal transmission function by the moiré pattern microstructure formed by two binary amplitude gratings of the same period equal to 100 µm and opening numbers equal to (1/2) and (1/3); the grating lines are angularly separated by 60 degrees in horizontal direction. WebAbstract We analyze the near-field behavior of binary amplitude/phase diffraction gratings, which modulate at the same time the amplitude and phase of the incident light beam. As it is expected, the distance between two consecutive self-images of the grating depends only on the period of the grating and the wavelength of the illumination. old world carthage scenario 3
