2. Infrared thermometer - Wikipedia

   en.wikipedia.org/wiki/Infrared_thermometer

   The most common infrared thermometer is the spot infrared pyrometer or infrared pyrometer, which measures the temperature at a spot on a surface (actually a relatively small area determined by the D:S ratio). These usually project a visible red dot onto the center of the area being measured that identifies the spot being measured, but plays no ...

   en.wikipedia.org/wiki/Non-contact_thermography

   Non-contact thermography, thermographic imaging, or medical thermology is the field of thermography that uses infrared images of the human skin to assist in the diagnosis and treatment of medical conditions. Medical thermology is sometimes referred to as medical infrared imaging or tele-thermology and utilizes thermographic cameras. According ...

5. Thermography - Wikipedia

   en.wikipedia.org/wiki/Thermography

   For a non-contact temperature measurement, the emissivity setting needs to be set properly. An object of low emissivity could have its temperature underestimated by the detector, since it only detects emitted infrared rays. For a quick estimate, a thermographer may refer to an emissivity table for a given type of object, and enter that value ...

   This principle can be used also for non-contact [1] infrared non-destructive testing (IRNDT) of materials. [2] The IRNDT method is based on an excitation of a tested material by an external source, which brings some energy to the material. Halogen lamps, flash-lamps, ultrasonic horn or other sources can be used as the excitation source for the ...

7. Thermometer - Wikipedia

   en.wikipedia.org/wiki/Thermometer

   An infrared thermometer is a kind of pyrometer . All objects above absolute zero emit blackbody radiation for which the spectra is directly proportional to the temperature. This property is the basis for a pyrometer or infrared thermometer and thermography. It has the advantage of remote temperature sensing; it does not require contact or even ...
