Optical vs infrared imagers
WebActive IR systems use short wavelength infrared light to illuminate an area of interest. Some of the infrared energy is reflected back to a camera and interpreted to generate an image. Thermal imaging systems use mid- or long wavelength IR energy. Thermal imagers are passive, and only sense differences in heat. WebOn these images, clouds show up as white, the ground is normally grey, and water is dark. In winter, snow-covered ground will be white, which can make distinguishing clouds more …

WebInfrared remote sensing makes use of infrared sensors to detect infrared radiation emitted from the Earth's surface. The middle-wave infrared (MWIR) and long-wave infrared (LWIR) are within the thermal infrared region. … WebA thermal imaging camera uses infrared rays for capturing living beings. Unlike normal light, infrared rays cannot pass through glass or water. It will simply reflect upon hitting glass …
WebAsphalt roads, for example, are dark blue or black; gravel or dirt roads are lighter colors depending on their composition; and clean concrete roads are light in tone. The colors of … WebOptical imagery, also known as optoelectronics, uses the light spectrum to garner images of the surface of the earth. It works on the principle that when sunlight falls on the earth’s surface, much of it is reflected in the outer spheres.
