[′min·ə·məm ri′zäl·və·bəl ′tem·prə·chər ‚dif·rəns] (thermodynamics) The change in equivalent blackbody temperature that corresponds to a change in radiance which will produce a just barely resolvable change in the output of an infrared imaging device, taking into account the characteristics of the device, the display, and the observer. Abbreviated MRTD.
