Thermogram of a traditional building in the background and a "passive house" in the foregroundInfrared thermography (IRT), thermal video or thermal imaging, is a process where a thermal camera captures and creates an image of an object by using infrared radiation emitted from the object in a process, which are examples of infrared imaging science.
A thermal imaging camera (colloquially known as a TIC) is a type of the thermographic camera used in firefighting. By rendering infrared radiation as visible light , such cameras allow firefighters to see areas of heat through smoke, darkness, or heat-permeable barriers.
Many thermal imagers, including some forward-looking infrared cameras (such as some LWIR enhanced vision systems (EVS)) are also uncooled. Medium-wave (MWIR) cameras operate in the 3–5 μm range. These can see almost as well, since those frequencies are less affected by water-vapor absorption, but generally require a more expensive sensor ...
Thermal imaging tech has become cheaper and homeowners are using it to track down heat loss.
Infrared vision is the capability of biological or artificial systems to detect infrared radiation.The terms thermal vision and thermal imaging [1] [2] are also commonly used in this context since infrared emissions from a body are directly related to their temperature: hotter objects emit more energy in the infrared spectrum than colder ones.
Infrared thermal imaging cameras or infrared cameras are essentially infrared radiation thermometers that measure the temperature at many points over a relatively large area to generate a two-dimensional image, called a thermogram, with each pixel representing a temperature. This technology is more processor- and software-intensive than spot or ...
