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. WebUnderstanding the Challenges of IR Sensing Optical Design. Infrared (IR) sensing is a critical technology with wide-reaching applicability. It is used to detect and measure the IR radiation emitted by objects and environments without direct contact or visible light. Since heat is the most common source of IR radiation, it is often associated ...

WebIn the simplest terms, hyperspectral imaging (HSI) is a method for capturing images that contain information from a broader portion of the electromagnetic spectrum. This portion … WebThe newest and upcoming geostationary passive imagers have thermal infrared channels comparable to those of more established instruments, but their spectral response functions still differ significantly. Therefore, retrievals developed for a certain type of radiometer cannot simply be applied to another imager. Here, a set of spectral band adjustment …
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 … 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…
