WebMar 15, 2024 · The main disadvantage of the electromagnetic acoustic transducer (EMAT) is low energy-conversion efficiency and low signal-to-noise ratio (SNR). This problem can be improved by pulse compression technology in the time domain. In this paper, a new coil structure with unequal spacing was proposed for a Rayleigh wave EMAT (RW-EMAT) to … WebApr 12, 2024 · The Rayleigh-wave dispersion energy images with good resolution can be directly extracted from the virtual-source shot gathers obtained by cross-correlation calculation. Comparing the results of the vertical and radial components, the difference in Rayleigh-wave dispersion images is still significant.

The seeded Rayleigh version was used to demonstrate the observation of transient flow features in a separated boundary layer region, which was excited with an oscillatory jet. Application of Rayleigh Scattering to Turbulent Flow with Heat Transfer and Combustion - Oct 07 2024 WebOutils. Les "systèmes de détection acoustique distribuée" (ou DAS pour distributed acoustic sensing) basés sur la diffusion de Rayleigh utilisent des fibres inutilisées de câbles à fibres optiques pour fournir une détection de signaux de contrainte de fréquence acoustique, tout au long de la fibre (d'où le qualificatif de "distribuée" ).

WebThe theoretical maximum optical resolution of optics is determined by diffraction effects of light which mainly depend on the wavelength of the light and the slit (aperture). According to the Rayleigh criterion (remaining contrast of approx. 15 per cent), two image points can still be distinguished when the distance of the points dx = 2 * 1.22 * f-stop * wavelength.
