Abstract

Space-borne LWIR FPA imaging system is an earth observation camera with waveband being 8.0~12.5μm, which adopts the technical scheme of two lines of 256×1 LWIR FPA detectors, 60K deep hypothermic Stirling cryocooler and on-axis two-reflection RC primary optical system. The imaging system has obtained good temperature sensitivity and acquired LWIR image with good image quality by configuring suitable detector cold shield and using -30°C cryogenic optical system and high performance information processing circuit.
