  • Dynamic offset correction in detector arrays
    Patent number: 6693279
    Abstract: A signal processing technique applied to the readout of two-dimensional detector arrays provides a dynamic correction mechanism for the varying offsets of the different elements of the array. The outputs of the elements are supplied to an offset correction circuit operative to compensate for the differences in the d.c. or low frequency outputs from a predetermined voltage wherein a fraction of the difference is subtracted at each successive cycle to gradually reduce the difference.
    Type: Grant
    Filed: December 13, 2001
    Date of Patent: February 17, 2004
    Assignee: InfraRed Integrated Systems Limited
    Inventors: Stephen George Porter, Graham Robert Jones, David Harry Broughton, John Fox, Bhajan Singh
