【摘要】 两轴反射式红外成像系统采用IRFPA探测器与平台分离的二次反射成像方案,成像实验表明该系统存在明显的像旋。首先利用基本坐标变换推导了系统的物像映射关系,然后用Matlab仿真证明理论像旋与实验像旋吻合。反求了解旋公式,经Matlab仿真证明有效。更多还原

【Abstract】 Clear image rotation is observed from imaging experiments of 2-axis IR Imager which uses twice reflecting method for separating the IRFPA form 2-axis platform.The mapping relationship between object and image coordinate is deduced with basic coordinate conversion formula.The theoretic image rotation is proved to be coincident with experiments by Matlab simulation.The eliminating rotation expression is deduced inversely for the track control method of 2-axis reflecting imaging platform and simulated in Matlab.更多还原
