Paper Abstract

Attainment of critical low noise performance of integrated focal plane subsystems (FPS) has been a difficult challenge, particularly the electrical interface between cryogenic and room temperature components. This paper presents a focal plane architecture for high performance scanning HgCdTe sensors which simplifies this interface and uses optical interconnects for improved noise immunity. Hardware testing has demonstrated operation at both component and integrated levels. Integrated FPS tests established noise as low as 50 (mu) V which is our goal. Our next step will be to evolve the FPS to demonstrate a fully flight compatible configuration.
