Diffraction-limited system — Memorial to Ernst Karl Abbe, who approximated the diffraction limit of a microscope as , where d is the resolvable feature size, λ is the wavelength of light, n is the index of refraction of the medium being imaged in, and θ (depicted as α in the … Wikipedia
Aperture masking interferometry — is a form of speckle interferometry, allowing diffraction limited imaging from ground based telescopes. This technique allows ground based telescopes to reach the maximum possible resolution, allowing ground based telescopes with large diameters… … Wikipedia
Diffraction — Computer generated intensity pattern formed on a screen by diffraction from a square aperture … Wikipedia
Numerical aperture — The numerical aperture with respect to a point P depends on the half angle θ of the maximum cone of light that can enter or exit the lens. In optics, the numerical aperture (NA) of an optical system is a dimensionless number that characterizes… … Wikipedia
Coherent diffraction imaging — A diffraction pattern of a gold nanocrystal formed from using a nano area beam of coherent X rays. This reciprocal space diffraction image was taken by Ian Robinson s Group to be used in the reconstruction of a real space coherent x ray… … Wikipedia

Airy disk — Computer generated image of an Airy disk. The gray scale intensities have been adjusted to enhance the brightness of the outer rings of the Airy pattern … Wikipedia
Optics — For the book by Sir Isaac Newton, see Opticks. Optical redirects here. For the musical artist, see Optical (artist). Optics includes study of dispersion of light. Optics is the branch of … Wikipedia
Optical resolution — This article is about optical resolution in optics. For the method of separating enantiomers in chemistry, see Chiral resolution. Optical resolution describes the ability of an imaging system to resolve detail in the object that is being imaged.… … Wikipedia
Superlens — A superlens, super lens or perfect lens is a lens which uses metamaterials to go beyond the diffraction limit. The diffraction limit is an inherent limitation in conventional optical devices or lenses.[1] In 2000, a type of lens was proposed,… … Wikipedia
