ABSTRACT:
A focal plan array system of the bolometer type which comprises: (a) an array of i×j pixel detectors of the bolometer type for sensing scenery radiation; (b) a case which accommodates said array of detectors, said case having a front window that provides exposure to the sensing element of all the i×j pixel detectors to radiation coming from the scenery; (c) at least one blind detector of the bolometer type within the case in a column j+1 for sensing case radiation, the sensing elements of said at least one detector are irradiated by one or more reference surfaces whose radiation is proportional to the case radiation; (d) reading circuitry for reading indication for the scenery radiation as sensed by each of the i×j detectors of the array, and for reading indication for the case radiation as sensed by said at least one blind detector; and (e) compensation circuitry for compensating each of said scenery radiation indications of each detector for the effects resulted from the case radiation, based on the case radiation indication as sensed by said at least one blind detector.
