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. … Multispectral imaging measures light emission and is often used in detecting or tracking military targets. In 2003, researchers at the United States Army Research Laboratory and the Federal Laboratory Collaborative Technology Alliance reported a dual band multispectral imaging focal plane array (FPA). This FPA allowed researchers to look at two infrared (IR) planes at the same time. Because mid-wave infrared (MWIR) and long wave infrared (LWIR) technologies measure r…

Optical Remote Sensing for Soil Mapping and Monitoring

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. WebBecause it is much safer than techniques that require ionizing radiation, like x-rays, optical imaging can be used for repeated procedures to monitor the progression of disease or the results of treatment. - Optical imaging is …
