Infraredteknologian
Infraredteknologian, meaning infrared technology, is the field that studies and applies infrared radiation, typically defined as light with wavelengths roughly from 700 nanometers to about 1 millimeter. It is commonly divided into near-infrared, mid-infrared, and far-infrared bands, each with different sources, detectors, and applications.
Infrared technologies rely on emitters such as specialized LEDs and laser diodes, and detectors including bolometers,
Applications include thermal imaging for building diagnostics, industrial inspection, medical thermography, astronomy, security and surveillance, automotive
Historical development began with William Herschel's discovery of infrared radiation in 1800, followed by advances in
Challenges include detector costs, cooling requirements for some systems, atmospheric absorption and scattering, and safety considerations
