Appeal No. 2006-1049
Application No. 09/667,826
14. through 20. (NO CHANGE)
21. An infrared imaging system as set out in claim [1] 2, further comprising
means, coupled to said output means, for analog to digital converting the corrected
detection signals and providing corresponding image data for each detector
element.
22. (NO CHANGE)
23. (CANCELLED)
24. An infrared imaging system [as set out in claim 23], 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 a plurality of readout cells equal in number to the
plurality of detector elements, 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, wherein said means for correcting
comprises an offset correction circuit in each readout cell of the readout
circuit and wherein each offset correction circuit comprises a plurality of
parallel connected circuit elements and means for selectively electrically
connecting said circuit elements into the readout cell in response to a stored
offset correction value corresponding to said readout cell; 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.
