Appendix: How Infrared Thermometry Works

 

 

Optics Field of View

Accurate measurement of temperature via infrared means depends strongly on the size of the object and the distance between the thermometer and the object. All optical devices (e.g. cameras, microscopes, infrared thermometers) have an angle of vision, known as a field of view or FOV, within which they see all objects. In particular, the thermometer will measure a fixed proportion of the energy radiated by all objects within its FOV. The user must guarantee that the distance between the thermometer and the object is defined so that only that object fills the FOV of the instrument.

Referring to Figure A-3, Objects “X” and “Y” are within the FOV of

the thermometer. The measured temperature would fall somewhere between the actual temperatures of the two objects. In order to measure the temperature of Object “X” accurately, Object “Y” would

need to be removed. In order to measure the temperature of Object “Y” accurately, the user would need to move closer to Object “Y”

until it completely filled the FOV of the thermometer. Alternatively, the user could measure the temperature of Object “Y” with a

thermometer with a smaller FOV.

The distance-to-spot size ratio (D⁄S) defines the field of view (FOV). Thus, a D⁄S = 10 gives you approximately a 1' spot size at a distance of 10'. For accurate spot size values, refer to the Field of View diagrams shown in Figures 3-3 through 3-8.
