1. Pushbroom Architecture Pushbroom scanners use CCD or CMOS arrays consisting of thousands of detectors aligned perpendicular to flight direction. Each detector continuously images a specific ground pixel line as satellite moves forward.
2. Detector Material Types Silicon CCD is used for visible/NIR (0.4–1.1 µm), InGaAs for SWIR (1–1.7 µm), and Mercury Cadmium Telluride (MCT) for thermal infrared. Each
Divergent evolution occurs when two or more related species become more different from each other over time, usually due to different environmental pressures. This results in the development of different adaptations that suit their environments. Example: Darwin’s Finches on the Galápagos Islands are an example of divergent evolution. Although they all evolved from a common ancestor, the finches’ beaks became specialized for different food sources on each island, leading to the formation of
