What is a temperature reference source and when / why do I need it?

A temperature reference is a “cavity” that is present in the field of view of the individual being screened. This reference device provides a constant steady temperature by which a Thermal imager can provide an absolute temperature measurement of the inner canthus(tear duct). Without the use of an accurate temperature reference, thermal imagers will only produce relative temperature measurements, which is not sufficient for human febrile screening according to ISO 13154-2017 and FDA guidances.
