中文摘要:针对目前基于单元探测器和线列探测器的红外成像仪不能较好兼顾大视场、高空间分辨率、高温度灵敏度的问题, 研制了一套基于非制冷型面阵红外探测器的大视场热红外成像仪, 实现了75°大视场、0.4 mrad空间分辨率和50 mK(NEΔT)温度灵敏度指标.建立了面阵摆扫图像畸变校正模型, 较好地解决了面阵摆扫图像定位精度低和图像拼接裂缝问题.研究成果对大视场面阵摆扫红外成像技术的发展具有重要的参考价值.

Aviation wide field thermal imaging technology based on array detector sweep-stop pattern
Abstract:The present infrared imager with unit or line detector cannot obtain wide field with high spatial resolution and high temperature sensitivity at the same time. To solve this problem, a set of wide field thermal infrared imager was developed based on uncooled array infrared detector. The system can realize the 75 ° large field of view, 0.4 mrad spatial resolution and 50 mk (NEΔT) temperature sensitivity. Furthermore, a geometric distortion correction model of array sweeping images was established to solve the low location accuracy and image mosaic crack problems.
