摘要
针对目前普通光电成像系统对伪装目标的探测和识别概率较低的状况,提出伪装目标的探测识别新技术研究。介绍了红外偏振成像系统的原理、组成和特点,研制的中波/长波红外偏振成像装置,其波段范围为3μm～5μm和8μm～12μm,线偏振度95%,消光比大于100∶1,给出了试验分析数据和偏振融合效果图。研究表明,采用红外偏振成像技术可以有效地实现对地面伪装目标的探测和识别。研究结果还可以扩展到对人工假目标、空中隐身目标等的探测和识别。
Due to the lower detection and recognition probability of camouflage target by current opto-electrical imaging systems,it is important to develop a new technology to detect and recognize the camouflage target.This paper introduces an infrared polarization imaging system,describes the principle,constitute and characteristics of the system.The waveband range of the developed infrared polarization imaging system is 3 μm ～5 μm/8 μm ～12 μm,the degree of linear polarization is 95%,and the extinction ratio is above 100∶1.The results of analysis data and polarization fusion image are given.These results indicate that the infrared polarization imaging system can effectively realize the detection and recognition of camouflage target.The results can also be extended into the detection and reorganization of artificial false objects and aerial stealth targets.
