摘要
红外焦平面阵列的非均匀性噪声是制约红外成像质量的主要因素。非均匀性校正是红外焦平面器件应用的一个关键技术,虽然现在已经提出多种基于场景的非均匀性校正方法,但是两点校正法因其实时性好,具有实用价值。文中讨论了两点校正法,并分别提出了利用查找表法和用CPLD实现焦平面探测器非均匀性校正的方案。
The non-uniformity in the infrared focal plane array has limited the quality of infrared imaging system. Non-uniformity correction is a key technology in the application of IRFPA. Though there are many scene-based non-uniformity correction methods, two points correction method is widely used because of its real-time processing. In this paper, the two points correction method is discussed, and then the designs of non-uniformity correction for IRFPA using function table and CPLD separately are presented.
