Rayleigh resolution

http://hyperphysics.phy-astr.gsu.edu/hbase/phyopt/gratres.html WebThis work presents an overview of spatial resolution criteria in classical optics, digital optics, and holography. Although the classical Abbe and Rayleigh resolution criteria have been thoroughly discussed in the literature, there are a few issues that still need to be addressed, e.g., the axial resolution criteria for coherent and incoherent radiation (which is a crucial …

WebIn general, active Rayleigh wave energy is higher frequency and provides for higher resolution but significantly shallower depths of investigation (on the order of 100 feet). Passive Rayleigh wave data provide poorer spatial resolution in the upper 100 feet but can be used to image the subsurface to depths in excess of several hundreds of feet.

The ability of a lens to resolve detail is usually determined by the quality of the lens, but is ultimately limited by diffraction. Light coming from a point source in the object diffracts through the lens aperture such that it forms a diffraction pattern in the image, which has a central spot and surrounding bright rings, separated by dark nulls; this pattern is known as an Airy pattern, and the central bright lobe as an Airy disk. The angular radius of the Airy disk (measured from the center … http://astronomy.tools/calculators/telescope_capabilities
