Appeal No. 2006-1049
Application No. 09/667,826
Appendix 2
Claims Of Original Patent Application 08/429,317, As Filed
1. An infrared imaging system, comprising:
an infrared focal plane array comprising:
a plurality of infrared detector elements arranged in an array;
a readout circuit electrically coupled to the plurality of detector
elements and comprising
means for biasing the plurality of detector elements so as to
provide separate detection signals corresponding to each
detector element in the array, in response to incident infrared
radiation and
means for separately correcting offsets in the detection signals
provided from the plurality of elements in the detector array to
compensate for nonuniformities in the detector elements; and
output means for providing the corrected detection signals as an
output of the focal plane array;
means for storing a plurality of offset correction values corresponding to the
plurality of detector elements; and
means for providing the offset correction values to said means for
correcting.
2. An infrared imaging system as set out in claim 1, wherein said means for
correcting comprises:
a correction circuit including a plurality of parallel connected circuit
elements; and
means for selectively electrically connecting said circuit elements into the
detector readout circuit in response to said stored offset correction values.
3. An infrared imaging system as set out in claim 2, wherein said plurality of
parallel connected circuit elements comprise a plurality of capacitors.
