  • Method and system for determining the rate of non uniformity of bolometer based systems
    Patent number: 7807969
    Abstract: A focal plan array system of the bolometer type having means for determining the rate of non-uniformity 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 a portion of column j+1 of blind detectors that are shielded from the scenery by a homogeneous reference surface; (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 non uniformity as sensed by said detectors in column (j+1); (e) a register for recording the radiation values as read from all the detectors within column (j+1); and (f) a processing unit for finding the standard deviation ? of all the values in said register, and for comparing the same to a predetermined threshold Q, wherei

  • Method and system for measuring and compensating for the case temperature variations in a bolometer based system
    Patent number: 7807968
    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 ra

  • Method and System for Measuring and Compensating for the Case Temperature Variations in a Bolometer Based System
    Publication number: 20090212220
    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 ra
