Rayleigh resolution
WebTo obtain a good image, point sources must be sufficiently far apart that their diffraction patterns do not overlap. The famous Rayleigh criterion describes the minimum distance … The imaging system's resolution can be limited either by aberration or by diffraction causing blurring of the image. These two phenomena have different origins and are unrelated. Aberrations can be explained by geometrical optics and can in principle be solved by increasing the optical quality of the system. On the other hand, diffraction comes from the wave nature of light and is determin…

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. 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.
