ASTM E1311 Minimum Detectable Temperature Difference for Thermal Imaging Systems
ASTM E1311 aims to determine the minimum detectable temperature difference capability of a compound that observes a thermal imaging system as a function of the angle subtended by the target.
Scope:
ASTM E1311 is a highly preferred method in terms of detecting a small spot within a large background. It basically shows the effectiveness of the thermal imaging system in this regard. MDTD values help in estimating detection capability.
Procedure:
In ASTM E1311, a standard circular target is used in contrast with a differential blackbody. It establishes a contrast between blackbody isothermal temperature for the target and blackbody isothermal temperature for the background. The temperature difference is initially at zero and then it is increased gradually for a limited duration. This critical temperature is basically called MDTD.
