近年来,被动红外成象系统已经开始广泛地应用于民品和军品中,而主动红外成象系统在许多实验室里也都巳使用了。实验研究和理论分析表明:无论是被动红外系统还是主动红外系统都各有所长,又各有所短。最近,美国马萨诸塞州工学院林肯实验室的Robert C.Harney认为它们是相辅相成的两种系统,同 In recent years, passive infrared imaging systems have begun to be widely used in civilian and military products, and active infrared imaging systems have also been used in many laboratories. Experimental research and theoretical analysis show that: Both the passive infrared system and the active infrared system have their own strengths and weaknesses. Recently, Robert C. Harney of the Lincoln Laboratory at the Massachusetts Institute of Technology found that they are two complementary systems,
