摘要
提出了一种被动式红外动态图像生成技术及相关装置.理论上分析了该装置的时间常数、空间分辨率和辐射对比度等参数,并进行了实验研究.实验测得转换器的空间分辨率为6lp/m m ,对比度大于100:1,时间常数～6m s.所得到的红外图像可用于对各种红外成像仪器和设备进行性能检测和标定。
A passive dynamic infrared generating technique as well as a related device was presented. The time constant, space resolutions and contrast ratio of the transducer were discussed theoretically and measured experimentally. Dynamic infrared images with space resolution of 6 lp/mm, contrast ratio better than 100:1,and time constant of about 6ms were realized in the experiment. The transducer can work for infrared image evaluation, calibration and dynamic infrared image simulation.
