摘　　要：在分析夜间自然辐射、目标和背景自身的辐射以及反射光谱特性的基础上,结合微光CCD摄像机的光电阴极响应谱线,提出光谱分割的设想,并据此设计单通道双谱微光夜视系统方案.依据光谱匹配及滤光技术的原理,提出光学薄膜设计及制作要求.对实际制作滤光膜的分谱特性进行了实验研究.结果表明:滤光薄膜的分谱效果对于单通道双谱微光系统提高目标识别概率是有效的.Analyzing spectrum characteristics of night natural radiation, target and background radiation and reflection,linking the spectrum response scope of CCD in low light level night vision system, then the spectrum intersected idea is presented and the project of single channel dual-spectrum night vision system is designed. Explaining the principle of spectrum matching and filtering technique,filtering film is designed and make. Experiment is done to study spectrum-segmentation characteristic of filtering film. The results show that the spectrum-segmentation effect of filtering film which is obtained in single channel dual- spectrum night vision system can improve target distinguish probability.
