Paper Abstract

This paper examines the potential benefits of using focal plane arrays in I-R detection systems. Two basic modes of operation are described together with their applicability to both the medium and long wavelength bands. We contrast the advantages and problems of two different readout schemes and consider their interaction with off focal plane electronics. We review theoretical ultimate limitations to performance and present more realistic theory predicting practically achievable results. Important array parameters such as uniformity, stability and dynamic range are considered together with constraints imposed by drive electronics, optics, cryogenic systems etc. Based on these considerations, our approach has been to confine the focal plane electronics to the functions of integration and mutliplexing, performing more power consuming tasks off the focal plane.
