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 ... WebOct 12, 2024 · each pixel of our camera. This unique feature is achieved by performing photon-number-resolving detection [30]. The sensitivity of this camera is limited by the photon uctuations, as stipulated by the Heisenberg uncertainty principle, and not by the Abbe-Rayleigh resolution limit [5,34]. In general, realistic imaging instruments deal with the

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).
