消像差条件在共形光学系统中的应用

Application of the Aberration Correction Criteria in Conformal Optical System Design

根据轴对称光学系统中的消像散条件探讨了共形整流罩结构中消像散万向节点位置的存在性.在此基础上,对共形光学系统中消像差万向节点位置进行了理论推导.软件分析结果表明,轴对称光学系统消像差条件对于共形光学系统的设计仍有良好的指导意义,由此得到的"消像差"共形光学系统的残余像差已处于实际成像系统的像差校正能力范围之内.

We have discussed the proper gimbal point position in conformal optical system based on the pupil astigmatism criteria. Then,we derive the best position of the aberration correction gimhal point by using aberration correction criteria in rotationally symmetrical system. The result proves the application potential of the aberration correction criteria in conformal optical system design and the dome＇s image quality has been improved greatly by properly choosing the position of the gimbal point.
