Rayleigh scattering size limit
WebThe Rayleigh criterion for the diffraction limit to resolution states that two images are just resolvable when the center of the diffraction pattern of one is directly over the first … WebDec 4, 2024 · The latter surpasses the Rayleigh scattering limit of silica glass fiber by 2 dB km −1 at the corresponding wavelength. Numerical simulations indicate that the loss level the authors achieve is still much higher than the ultimate loss limit caused by surface scattering of this HCF geometry, leaving plenty of room for further refinement.
