Paper Abstract

The use of charge transfer devices on the focal plane allows signals from a large number of detectors to be multiplexed onto a few video lines, thereby reducing the leadout complexity and making possible focal planes with many thousands of individual detectors, with a resultant increase in performance over present systems. Hybrid technology, which interfaces silicon CCDs with optimum infrared detector materials, offers a high performance, near term solution for advanced focal planes. The electrical and mechanical aspects of hybrid technology are addressed, and reasonable solutions are presented for both PC and PV detectors multiplexed by a CCD with minimum loss in S/N. The systems implications of this approach to large focal planes are described. Finally, experimental results obtained at Honeywell on detector and detector/CCD performance are presented. Progress in this area has been rapid, and the large hybrid focal planes will begin appearing in infrared systems in the next few years.
