摘要
本文讨论了图像运动对前视红外成像的影响,用光学传递函数理论推导出图像运动OTF的数学表达式,并计算了在正弦振动条件下的结果,分析表明红外前视仪平台抖动将造成图像严重模糊。
This paper describes the effects of image motion on FLIR system, and derives mathematical expressions of Image-Motion-OTF using Optical Transfer Functions theory. The computational results of OTF subjected to sinusoidal vibration are given. The analytical results illustrate that vibrations of a FLIR platform give rise to a smearing of the image seriously.
