Glossary of the most common terms used within the thermal profiling process.

The optical system of an infrared sensor collects the infrared energy from a circular measurement spot and focuses it on the detector. Optical resolution is defined by the ratio of the distance from the instrument to the object, compared to the size of the spot being measured (D:S ratio). The larger the ratio number the better the instrument's resolution, and the smaller the spot size that can be measured from greater distance.

Les émissivités dépendent de la longueur d'onde à laquelle on effectue la mesure. Reportez-vous au mode d'emploi pour connaître les longueurs d'onde auxquelles opère votre appareil. Attention : les valeurs suivantes dépendent de la nature actuelle du matériau et des conditions de mesure.
