2. Infrared thermometer - Wikipedia

   en.wikipedia.org/wiki/Infrared_thermometer

   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 ...

3. Pyrometer - Wikipedia

   en.wikipedia.org/wiki/Pyrometer

   A pyrometer, or radiation thermometer, is a type of remote sensing thermometer used to measure the temperature of distant objects. Various forms of pyrometers have historically existed. Various forms of pyrometers have historically existed.

4. Thermometer - Wikipedia

   en.wikipedia.org/wiki/Thermometer

   A thermometer has two important elements: (1) a temperature sensor (e.g. the bulb of a mercury-in-glass thermometer or the pyrometric sensor in an infrared thermometer) in which some change occurs with a change in temperature; and (2) some means of converting this change into a numerical value (e.g. the visible scale that is marked on a mercury ...

5. Pyrgeometer - Wikipedia

   en.wikipedia.org/wiki/Pyrgeometer

   A pyrgeometer is a device that measures near-surface infra-red (IR) radiation, approximately from 4.5 μm to 100 μm on the electromagnetic spectrum (thereby excluding solar radiation). It measures the resistance / voltage changes in a material that is sensitive to the net energy transfer by radiation that occurs between itself and its ...

6. Thermography - Wikipedia

   en.wikipedia.org/wiki/Thermography

   Hence, an excellent way to measure thermal variations is to use an infrared vision device, usually a focal plane array (FPA) infrared camera capable of detecting radiation in the mid (3 to 5 μm) and long (7 to 14 μm) wave infrared bands, denoted as MWIR and LWIR, corresponding to two of the high transmittance infrared windows. Abnormal ...

7. Active thermography - Wikipedia

   en.wikipedia.org/wiki/Active_thermography

   It can significantly reduce acquisition costs of the measurement system. The IR nondestructive testing system are usually modular. It means that various excitation sources can be combined with various infrared cameras and various evaluation methods depending on application, tested material, measuring time demands, size of a tested area, etc.
