Infrarotfarben

Infrarotfarben, also known as false-color infrared or color-infrared (CIR) imagery, are composite images created by assigning visible colors to data captured in the infrared part of the electromagnetic spectrum. While the human eye can only perceive light in the visible spectrum, cameras equipped with infrared sensors can detect radiation beyond what we can see, typically in the near-infrared (NIR) range. Infrarotfarben imagery is produced by mapping different infrared bands, or combinations of infrared and visible bands, to the red, green, and blue channels of a standard color image. This process can reveal characteristics of objects that are not apparent in natural-color photographs. For instance, healthy vegetation strongly reflects near-infrared light, causing it to appear in bright reds or pinks in Infrarotfarben images, whereas unhealthy or stressed vegetation reflects less NIR and might appear in darker shades. Water typically absorbs most NIR radiation, so it often appears very dark or black. This technique is widely used in remote sensing for applications such as vegetation health monitoring, land cover classification, geological surveys, and even medical imaging. The specific colors assigned can vary depending on the chosen color scheme, but the principle remains the same: to visualize infrared information in a way that is interpretable to humans.
