    Vocabulary Absolute zero Absolute zero refers to the temperature of -273.15°C (0 Kelvin = -459.69°F). Absolute zero is an ideal state, in which all material’s atomic movement completely stopped. At this temperature, objects have no thermal energy. Kelvin [K] Kelvin is a general temperature unit; an Object of 0 K temperature reaches absolute zero (-273.15°C).
  • Page 116 more energy than objects with a lower temperature. Infrared radiation an object absorbs is usually transformed into thermal energy of its own and gets re- emitted. Therefore, an object’s emissivity is linked to its absorptivity. Radiation Any object with a temperature higher than absolute zero is continuously radiating heat in the form of an electromagnetic wave.
  • Page 117 A colored body radiator refers to materials whose emissivity changes based on wavelength and temperature difference. An object could have a few different emissivities. Most metals are colored body radiators. (Ex: Aluminum’s emissivity rises when heated) Thermal Imager Thermal imager refers to devices that can detect radiations of infrared-band wavelength and convert the invisible infrared radiation into visible pictures.
  • Page 118 lens can measure the temperature distribution of a larger field, and a telephoto lens can observe finer detail in distance. Germanium, silicon, and zinc selenide are good materials for making camera lenses because they have high infrared transmittance. Field of View (FOV) Field of view refers to the vertical and horizontal angle objects project themselves in the thermal imager MFOV...
  • Page 119 It refers to how close the measured result is to the reference. Ex: if the actual temperature of an object surface is 100 ℃ , and the accuracy is ±2 ℃ , then the measured temperature would be 98 ℃ —102 ℃ Verification Verification is a process, which compares the measurement result and the object’s standard value.
  • Page 120 relatively low emissivity, and there are heat sources nearby, it’s a good idea to turn on RTC. Condensation It refers to the process of gas turning liquid. When an object’s surface temperature is lower than the ambient temperature, the moisture in the air will condense into water droplets on the surface.
  • Page 121 It reflects an object’s ability to convey heat by convection. Definition: when the temperature difference between fluid and solid surface is 1 k, the amount of energy been conveyed by convection of 1 unit area in a second Kirchhoff’s radiation law Kirchhoff’s radiation law describes the relationship between an object’s emissivity and absorptivity of a certain wavelength: at thermal equilibrium, an object’s absorptivity of thermal radiation is equal to its emissivity at the same...
