摄像机在曝光时间内与目标的相对运动会产生像质模糊，且速高比(或速距比)越大，模糊状态越严重。目前，光学式像移补偿方法主要采用反射镜元件，针对其存在像旋校正机构复杂、运动定位控制难度大、摆扫式易产生光学振荡等缺点，提出了应用旋转双光楔系统进行像移补偿的新方法。建立了双光楔系统的动态作用矩阵数学模型，分析了光楔组件在各种独立运动状态下的出射光矢量轨迹，进行了软件仿真。根据实际的像移补偿需求，给出了双光楔系统的设计结果及控制方法。仿真和分析结果表明：双光楔系统具有结构紧凑、控制方法简单、运动平稳、补偿能力强等显著优点，对于大速高比(或速距比)的应用场合具有重要的实际意义。

Image blur dues to the relative motion with the target in the camera exposure time, it would be worse while the ratio of speed and height(or speed and distance) increased. At present, the optical image motion compensation method bases mainly on the reflective element. In order to overcome the disadvantages of complicated image rotation corrected mechanism, difficult position location and optical vibration occurred by the swing scanning, a new method based on rotating double optical wedge was proposed, the dynamic working matrix was built, the emergent light vector′s trajectory was analyzed and simulated. According to the actual image motion compensation demand, the double optical wedge designing result and controlling method were presented. Through analysis and simulation, the results show that this method has significant advantages such as compact structure, easy controlling method, stable motion state, high compensation capacity, etc. It has very important practical value for the occasions of the greater ratio of speed and height (or speed and distance).
