WebBoth equations are in fact structurally similar with Abbe limit given by d = λ 2 N A. And Rayleigh limit given by d = 1.22 λ 2 N A = 0.61 λ N A. where lambda is the wavelength and N A the numerical aperture of the light collecting lens. The factor 1.22 comes from the definition of Bessel function of 1st kind,the fact that 1st minima of the ... WebMar 21, 2024 · 1. Introduction. Rayleigh waves, in the ultrasonic frequency range, are widely used for non-destructive evaluation of materials for their mechanical and structural properties [1,2].In geophysics and geotechnical engineering, these waves are used for the characterization of subsurface hydrocarbon deposits and to explore Earth’s interior.

WebThe name “Rayleigh scattering” is mostly associated with light scattering by molecular and atomic gases and the related question “Why is the sky blue?”1,2 In addition, the name Rayleigh is commonly attached to scattering by small particles in the expressions “Rayleigh regime” or “Rayleigh limit,” in which small refers to a size ... WebAnother Rayleigh scattering-based approach is the optical frequency-domain reflectometry (OFDR) with the frequency scanning, in which the probe signal is a continuous frequency modulated optical wave instead of a pulsed signal as in OTDR [].In contrast to OTDR, the OFDR systems have relatively higher power per frequency components, so a more …
