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 ... WebRayleigh’s criterion is extensively used in optical microscopy for determining the resolution of microscopes. This criterion imposes a resolution limit that has long been held as an impediment for studying nanoscale biological phenomenon through an optical microscope.

WebJul 7, 2024 · Resolution. Image resolution is typically described in PPI, which refers to how many pixels are displayed per inch of an image. Higher resolutions mean that there more pixels per inch (PPI), resulting in more pixel information and creating a high-quality, crisp image. Images with lower resolutions have fewer pixels, and if those few pixels are ... WebThe Rayleigh criterion for the diffraction limit to resolution states that two images are just resolvable when the center of the diffraction pattern of one is directly over the first minimum of the diffraction pattern of the other.
