Standard Practice for Minimum Resolvable Temperature Difference for Thermal Imaging Systems

Importancia y uso:

5.1 This practice relates to a thermal imaging system's effectiveness for discerning details in a scene.

5.2 MRTD values provide estimates of resolution capability and may be used to compare one system with another. (Lower MRTD values indicate better resolution.)

5.3 Due to the partially subjective nature of the procedure, repeatability and reproducibility are apt to be poor and MRTD differences less than 0.2 °C are considered to be insignificant.

Note 1: Values obtained under idealized laboratory conditions may or may not correlate directly with service performance.
