Sparrow is a MWIR detector and video-core module based on SCD’s Blackbird 640×512/10μm read-out integrated circuit (ROIC) and it’s High Operating Temperature (HOT) XBn-InAsSb Focal Plane Array (FPA). The Sparrow detector enables versatile high-end imaging over a wide spectral range, from the SWIR to the MWIR, and the high FPA operating temperature of 150K allows the use of a low Size, Weight and Power (SWaP) cooler. The Proximity electronics board controls the detector and cooler, and outputs raw video at a frame rate of up to 180Hz. The same board also has thermal imaging video-core capabilities at 60Hz with sub-frame video latency, user-configurable advanced image processing algorithms, and a variety of output video formats. The detector module is equipped with a miniature split-linear Stirling cooler, and a small and stiffened Dewar, which, together with the Proximity electronics board, are compactly harnessed to a low weight metal frame, designed to withstand harsh conditions and allow for easy and efficient integration to the optical system. The module is optimized for a wide range of low SWaP applications, with a volume of 58×62×42 mm3, a weight of 300g, and a power consumption of 5W at room temperature. In this work we present key results from the Sparrow detector and video-core, which are now in low rate production at SCD.
