Appeal No. 2006-1049
Application No. 09/667,826
24. An infrared imaging system as set out in claim 1, 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.
25. An infrared imaging system as set out in claim 24, further comprising a
memory for temporarily storing image data corresponding to all the detector
elements of the array.
26. 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 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.
27. An infrared focal plane array, comprising:
a plurality of detector elements configured in a two dimensional array; and
a readout circuit electrically coupled to said plurality of detector elements
