Paper Abstract

The development of the direct injection unit cell architecture with a direct readout has produced several varieties of high-performance large-area staring arrays. These arrays satisfy almost all foreseeable missile applications. The uniformity, noise, and linearity lend themselves to low-complexity, high-performance missile systems. These readout integrated circuits (ROICs) are demonstrated with InSb over a spectral band of 0.5 to 5.5 um with NE(Delta)T of 17 mK under ambient tactical and low-background space conditions. Hybridization of eighteen 128 x 128 ROICs with LWIR HgCdTe resulted in an average NE(Delta)T of 21 mK. The new EPIC substrates yielded high-performance 256 x 256 LWIR HgCdTe capable of withstanding 2000 thermal cycles. The simple interface requirements of the /ST ROIC coupled with the high yield and extremely high operability show promise for future low-cost commercial IR systems.
