红外焦平面 非均匀校正 两点线性校正法 误差 infrared focal plane nonuniformity correction tow-point linear correction error
摘要
所有的红外焦平面阵列必须进行非均匀性校正.两点线性校正法是最先开发研究的方法之一,也是使用最广泛的校正方法.然而由于响应率的非线性和噪声等原因两点线性校正后仍然存在误差.本文分析并计算了两点线性校正误差,并指出了减少非均匀校正误差的方法.
Abstract
All infrared focal plane arrays (IRFPAs) require nonuniformity correction. Two-point linear correction is one of the earlier studied and widely used methods. However, nonlinearity of the responsibility and noise result in the nonuniformity error. This paper describes and calculates the error resulted from noise and nonlinearity. A method to reduce the nonuniformity error is also presented.
