| minimum resolvable temperature difference [`min·ǝ·mǝm ri`zäl·vǝ·bǝl `tem·prǝ·chǝr ´dif·rǝns] 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. |
