Abstract

The integration of successive frames from a 128 x 128 infrared detector array is complicated by (1) the large number (i.e. 16,384) of detector elements in the array, (2) the necessity of achieving computational precisions better than 0.01%, and (3) the space and power limitations that are implied by a 77°K focal plane location for the processing circuitry. The design of an analog frame integrator to meet the above requirements is discussed. In addition, a correlated triple sampling circuit, which is incorporated in the frame integrator and which can be adapted to a variety of read-out techniques, is described.
