Thermography — Infrared Thermography, thermal imaging, or thermal video, is a type of infrared imaging science. Thermographic cameras detect radiation in the infrared range of the electromagnetic spectrum (roughly 900 ndash;14,000 nanometers or 0.9 ndash;14 µm) … Wikipedia
Pyrometry — is the non contact measurement of the temperature of an object, by measuring its self emission and emissivity. An apparatus that measures the temperature by means of pyrometry is called a pyrometer or optical pyrometer.Emissivity is a measure of… … Wikipedia
Black body — As the temperature decreases, the peak of the blackbody radiation curve moves to lower intensities and longer wavelengths. The blackbody radiation graph is also compared with the classical model of Rayleigh and Jeans … Wikipedia
Stefan–Boltzmann law — The Stefan–Boltzmann law, also known as Stefan s law, states that the total energy radiated per unit surface area of a black body in unit time (known variously as the black body irradiance, energy flux density, radiant flux, or the emissive… … Wikipedia
Building insulation — refers broadly to any object in a building used as insulation for any purpose. Whilst the majority of insulation in buildings is for thermal purposes, the term also applies to acoustic insulation, fire insulation, and impact insulation. Often an… … Wikipedia
Multi-layer insulation — Closeup of Multi layer insulation from a satellite. The metal coated plastic layers and the scrim separator are visible. Multi layer insulation, or MLI, is thermal insulation composed of multiple layers of thin sheets often used on spacecraft. It … Wikipedia
Building insulation materials — A selection of insulation materials can aid in building insulation. All of these are based on standard principles of thermal insulation. Materials used to reduce heat transfer by conduction, radiation or convection are employed in varying… … Wikipedia
