Optical resolution describes the ability of an imaging system to resolve detail, in the object that is being imaged. An imaging system may have many individual components, including one or more lenses, and/or recording and display components. Each of these contributes (given suitable design, and adequate alignment) to the optical resolution of the system; the environment in which the imagin… http://hyperphysics.phy-astr.gsu.edu/hbase/phyopt/diflim.html

WebPresumably, you have come across TV ads that say that a 4K (or Ultra High-definition/UHD) TV with a resolution of 3840 X 2160 produces better images than a Full HD TV with a resolution of 1920 X 1080. WebJun 11, 2024 · The basic GSD calculator is: GSD = Orbital Height x Pixel Size / Focal Length. Therefore, the further the satellite is from the earth and the larger the pixel size, the bigger the GSD value. A bigger GSD results in an image with less visible detail. To compensate for the bigger GSD, one can increase the focal length of the instrument; however ...

WebJan 2, 2010 · The Rayleigh roughness criterion is a widely used means to estimate the degree of roughness of a considered surface. Considering the phase difference between two rays scattered from separate points of the surface, this depends on the roughness height, the incident angle and, inversely, on the radiation wavelength (λ).
