"The Galileo camera is a fully self-contained infrared camera. Features such as compact size, single DC input voltage operation, and remote control enable Galileo to be compatible with ta variety of applications, notably remote sensor functions.
This camera incorporates Amber's 256x256 InSb Snapshot focal plane array into a high reliability, cryo-cooler/dewar assembly with at-dewar electronics and dedicated signal processing electronics. The AE173 FPA furnishes a detector pitch of 30 µm, and implements a centroid windowing feature, allowing full 256x256 operation at 120 Hz, or 128x128 at 480 Hz, or 64x64 (1,400 Hz) subarrays.
Galileo's signal processing electronics are based on a three-board set that includes uniformity correction, power, and video. The camera is designed to accommodate separation of the sensor engine from the signal processing electronics via an interconnect cable up to ten meters in length with the appropriate shielding.
The camera furnishes composite analog video in RS-170 or PAL formats, and 12-bit digital data in parallel differential or serialized ("hotlink") high-speed formats. Additional features such as FPA control via external synchronization signals promote camera use in a variety of special applications. "
