termiskeinfrarøde

Termiskeinfrarøde, also known as thermal infrared, refers to the portion of the electromagnetic spectrum that corresponds to thermal radiation emitted by objects with temperatures above absolute zero. This radiation is characterized by wavelengths ranging from approximately 1 to 100 micrometers, which is longer than visible light but shorter than microwave radiation.

Thermal infrared radiation is emitted by all objects with a temperature above absolute zero due to their thermal energy. The intensity and spectral distribution of this radiation depend on the object's temperature and emissivity. Higher temperatures result in a shift towards shorter wavelengths, while lower temperatures shift the spectrum towards longer wavelengths.

Thermal infrared imaging, or thermography, is a technique used to detect and visualize thermal radiation. It is commonly employed in various fields, including medicine, industry, and security. In medicine, thermography is used to detect abnormalities in the body's temperature distribution, which can indicate underlying health issues. In industry, it is used for non-destructive testing and quality control, as well as for monitoring equipment and processes. In security, thermal imaging is used for night vision and surveillance.

Thermal infrared technology has seen significant advancements in recent years, with the development of more sensitive detectors and improved image processing techniques. These advancements have led to the creation of compact, portable, and cost-effective thermal imaging devices, making thermal infrared imaging more accessible and widely used.
