Abstract

The Osprey-E sensor module consists of an integrated detector-cooler assembly (IDCA) and custom proximity electronics mounted in a lightweight, ruggedized housing. Based on the half-TV format Osprey FPA, it implements recent improvement in SELEX Galileo's array hybridization technique. Ongoing tests have shown that performance is not significantly degraded after more than 5000 cooldown cycles. The FPA exploits SELEX Galileo's High Operating Temperature (HOT) HgCdTe (MCT) and is optimized for operation at 110K. Very low levels of defective pixels (<0.003%) have been achieved at this temperature. The proximity electronics are a new design that originates from SELEX Galileo's Centre of Excellence in Infrared Detectors. The electronics provide all the necessary supplies and signals for detector operation and digitize the detector output into 14-bit digital video. The sensor has been developed to offer a very lightweight, rugged camera core particularly suited to airborne applications.
