Principle:

 An infrared (IR) thermometer contains an optical sensor, usually a thermopile, which can detect the infrared emissions from any hot object. The magnitude and spectrum of infrared energy emitted depends on:

a.) internal temperature of the body

b.) temperature of the thermometer, which is also radiating IR energy

c.) emissivity, which describes the efficiency of the surface for radiating electromagnetic radiation and is a dimensionless number between 0 (smooth shiny surface) and 1 (dark rough surface)

d.) filtering effect of optical components, including the probe cover.

Infrared ear thermometers are designed to sense the temperature of the tympanic membrane within the ear. The measured temperature is an average across the visualised area. The field of view may encompass adjacent ear structures, approximately 2 Calsius cooler than the tympanic menbrane (typically 37.3 Calsius). An instrumentation offset is usually applied which incorporates information about the thermometer's temperature and filtering effect of the optical components. Some devices also try to correct for the effect of averaging( making assumptions about the relative size of the tympanic membrane in the field of view.)

Forehead thermometers repeatedly sample the skin temperature seeking peak values, caused by the presence of the temporal artery lying under the surface. Inftrumentation offset values and physiological offset values are then applied to predict the temperature at another site, usually oral. All these devices use computational software to rapidly predict the temperature but the algorithms will vary between different types as they are based on their own clinical trials.
