| 摘 要： | 首先根据光电成像系统与目标的几何关系,分析了积分时间内载体运动在焦平面上产生的像移;然后从调制传递函数的角度分析了运动对成像系统性能的影响,最后分析了运动对光电成像系统分辨率的影响.结果表明:载体的角运动会严重影响光电成像系统性能,必须将积分时间内载体的角运动控制在探测器瞬时视场内.

| Abstract: | Image motion produced by the carrier movement on the focal plane within integration time is analyzed according to the geometric relation between photoelectric imaging system and target.Then the effect of the carrier movement on the modulation transfer function(MTF) of imaging system is discussed.Finally,the effect of the carrier movement on the resolution of photoelectric imaging system is also analyzed.The results show that angular motion of the carrier would bring serious influence to photoelectric imagin... |
