Abstract
In accordance with the present invention, a microbolometer focal plane array is provided with at least one thermally-shorted microbolometer detector that is thermally shorted to the microbolometer focal plane array substrate. A characteristic relationship is empirically derived for determining a corrected resistance value for each detector of the microbolometer focal plane array in response to radiation from a target scene as a function of the corresponding detector resistance value, the thermally-shorted microbolometer detector resistance value, and the empirically derived characteristic relationship.
