The SBIR Focal Plane Array Test System (FPATS) is designed to support characterization and calibration of up to nine uncooled focal plane arrays (FPA’s) simultaneously. The FPA ambient and scene temperatures are independently controlled, allowing for testing at multiple combinations of FPA and scene temperatures. 

The system includes four main sub-assemblies, an Ambient Source Assembly (FPA temperature control), an Aperture Plate Assembly (f/1 cone), Scene Source Assembly (extended area blackbody), and the Housing Assembly. The Ambient Source Assembly and the Scene Source Assembly are controlled by two 2U 19-inch rack mounted controllers. A standalone recirculating chiller that provides temperature controlled fluid to the heatsinks of these assemblies is also included in the FPATS.
