1. A method for reconstructing a dithered image, comprising:

  • (a) applying a detector array to an image, the image comprising a plurality of image sections, the detector array comprising a plurality of detectors, each detector having a plurality of dither positions, each dither position associating the detector with one of the image sections;

    (b) adjusting each detector to a first dither position;

    (c) for each detector, obtaining a first signal corresponding to an associated image section for the first dither position;

    (d) adjusting each detector to a subsequent dither position;

    (e) for each detector, obtaining a subsequent signal corresponding to an associated image section for the subsequent dither position;

    (f) for each image section, determining an estimated output signal by comparing the signals obtained in steps (c) and (e) corresponding to the image section and further comparing the signals obtained in steps (c) and (e) for each detector having a dither position associating the detector with the image section; and

    (g) generating an output comprising the estimated output signals for the image sections.
