This paper provided thin lens aberrations for anamorphic lenses, including the central thin lens aberrations, the central Lagrange invariant shift, the central conjugate shift, and the central pupil shift. Based on thin lens theory and the paraxial lens module, the aberration of the anamorphic lens system can be easily corrected. The central Lagrange invariant shift can be used for aberration correction for an anamorphic zoom lens system. In order to make a concise expression for the central conjugate shift, eight aberration coefficients are introduced: D¯, D¯, D¯, D¯, D¯, D¯, D¯, and D¯. Similarly, four aberration coefficients are introduced for the central pupil shift: D, D¯, D, and D¯. A simulation is conducted that proves numerically the validity of the thin lens aberrations for an anamorphic lens system.
本文给出了变形透镜的薄透镜像差，包括中心薄透镜像差、中心拉格朗日不变量偏移、中心共轭偏移和中心光瞳偏移。基于薄透镜理论和近轴透镜模块，变形透镜系统的像差可以很容易地得到校正。中心拉格朗日不变量偏移可用于变形变焦透镜系统的像差校正。为了简洁地表示中心共轭偏移，引入了八个像差系数：D¯、D¯、D¯、D¯、D¯、D¯、D¯和D¯。类似地，为中心光瞳偏移引入了四个像差系数：D、D¯、D和D¯。进行了一项模拟，从数值上证明了变形透镜系统薄透镜像差的有效性。
