基于Flood方法的电阻阵列非均匀性校正方法研究

非均匀校正技术是电阻阵列红外动态景象投射器的关键技术之一,国外早已在该领域取得了突破性研究成果,已实现了精确校正,并且得到工程化应用。而国内研究则进展较缓,校正精度不足。本文以Flood测试法为基础,以盲复原迭代方法为研究对象,结合国内研究现状对该方法进行了完善和验证。实现在无需估计点扩散函数的条件下,利用对探测数据的处理消除了观测噪声和边缘效应的影响并且实现了残余非均匀性小于1%的校正。

Nonuniformity Correction for Resistance Arrays Based on Flood Method

Non-uniformity correction technology is a key technology of resistance array infrared dynamic scene projector.Several developed countries have achieved breakthrough results,especially in this technology,which have been accurately corrected and applied in engineering.However,there have been few domestic studies,and the correction accuracy is insufficient.Based on the flood test method,this paper takes the blind recovery iteration method as the research object and combines the results of domestic studies to improve and verify the method.Without estimating the point spread function,the effect of observation noise and edge effect is eliminated by processing the detection data,and the residual nonuniformity is corrected to be less than 1%.
