摘　　要：研制了一套轻小型面阵摆扫热红外成像系统,采用面阵探测器并结合系统光学元件在翼展方向的摆扫实现了宽视场、高分辨率成像,利用环架反向补偿纠正了横滚姿态扰动导致的视场偏移。通过功能验证试验,获取了视场无偏移的宽视场高分辨率图像。系统光机结构简单,体积、重量优势明显,在轻小型无人机热红外遥感方面应用前景广阔。研究成果对推动无人机载热成像技术向宽视场、高分辨率方向发展具有一定的参考价值。A light-small whiskbroom scanning thermal imaging system with area-array detector was developed. Wide field of view（WFOV） and high resolution imaging was realized by area-array detector and whiskbroom scanning of the system optical element in the wingspan direction. At the same time, the field of view（FOV） shift caused by roll attitude disturbance was corrected by reverse compensation of the gimbal. Then WFOV and high resolution image without FOV shift was obtained through a functional verification test. This imaging system has simple optical-mechanical structure and obvious advantages in volume and weight, and has a broad application prospect in thermal infrared remote sensing of minitype nnmanned aerial vehicle （UAV）. The result is valuable for pushing the development of thermal imaging technology of UAV to WFOV and high resolution.
