5. Techniques of Infrared (IR) Thermometers 5-1 Field of View (FOV) Ratio = Distance to Spot (D:S) Ratio The field of view is the angle of vision at which the instrument operates, and is determined by the optics of the unit. The F OV is the ratio of the distance from the target to the target diameter.
5-2 Emissivity Emissivit y is the abilit y of an object to emit or absorb IR energy. Perfect emitter s have an emissivit y of 1, emitt ing 100% of incident energy. An object w ith an emissivity of 0.8 will absorb 80% and reflect 20% of the incident energy.
