ABSTRACT:
A focal plane array for scanned imaging systems provides an increased dynamic range by encoding analog differences between scene pixel amplitudes at a detector unit cell. Charge Coupled Device (CCD) differentiators are utilized to encode the pixel deltas at the unit cell. These deltas are summed and transmitted in time delay and integration fashion with a CCD readout register. DC sense edge detector information is read out independently of the register AC signals, and thus provides a level from which to begin integration of the pixel deltas. The DC and AC scene information are contained in the reconstructed video.
