FPGA实现红外焦平面的非均匀性校正
Implement of Pyroelectric IRFPA Nonuniformity Correction Using FPGA
摘要
红外焦平面阵列(IRFPA)普遍存在着响应度的非均匀性问题,极大的限制了凝视红外系统的探测性能,本文先分析了红外焦平面阵列非均匀性的成因,然后讨论了非均匀性校正的方法,最后针对热释电红外焦平面非均匀性产生的特点,提出了用FPGA实现其非均匀性校正的方案.
Abstract
IRFPA Nonuniformity exsists in all IRFPA detectors,and it limits the performance of infrared imaging detectors.Here we analyse the cause of the nonuniformity for IRFPA at first, then give some methods for NUC.At last the design of NUC for pyroelectric IRFPA using FPGA is presented.
