| 摘 要： | 利用热传导方程,从理论上探讨了基于光纤面阵红外图像生成的机制,分析了光纤端面吸收膜表面处红外辐射的时间常数随吸收膜材料的发射率、光纤材料热传导系数、光纤材料比定压热容、光纤材料密度,以及激发光的功率和脉宽的变化规律.提出了一种被动式红外动态图像生成技术,其空间分辨率只受可见光图像的分辨率和光纤面阵总的像束数影响.为实验装置的设计提供了理论依据.应用该原理制作的图像转换装置所得到的红外图像可用于对红外成像仪器和设备进行动态性能检测和标定,以及红外成像仿真实验.

| Abstract: | A technique of dynamic infrared image generation was presented in this paper. The physical and mathematical models of the radiation were established for analyzing the performance principle of the transducer.The solution of heat transfer equation had been derived.The function of the fiber panel transducer was discussed, and the factors which affected the time constant and spatial resolution of the transducer were analyzed. A fiber panel structure was put forward to improve the spatial resolution of the transducer. The infrared image generated by this apparatus could be used for simulation test of infrared imaging guidance missile and also be used to measure the uniformity and dynamic characteristics of many infrared image instruments. |
