The current advances in density and performance of 2-D staring IR FPAs are now enabling the development of solid state non-scanning imagers of TV quality. Significant cost reductions with performance improvements are accomplished using these new high density staring arrays. This paper reports on the development of an IR imager using a new system oriented 256 X 256 InSb hybrid FPA. Two-dimensional InSb hybrid FPAs were first reported on in 1978 at the IEDM with papers describing 32 X 32 arrays using indium bumps and CCD multiplexers. This basic technology has progressed to 256 X 256 and large arrays using HgCdTe and InSb detectors. The arrays are still interconnected with indium bumps but rely on improved MOS switched readouts using the latest in CMOS process technology. Significant improvements in performance and operability as well as system implementation have also been made.
