提出利用变焦系统设计思想来快速实现复杂航空相机光学系统消热差设计的新方法，基于光学式补偿基础，建立了变焦设计与消热差设计的对应关系模型。设计常温下满足成像质量要求的消色差的良好光学系统；建立多个变焦位置，分别对应于不同的工作温度状态；通过优化设计快速发现材料组合，满足宽工作温度范围内像质均良好的要求。利用该方法设计了一工作于0.45～0.70 μm波段，焦距650 mm，F数为5.6，视场为5.5°的航空CCD相机光学系统，结果表明系统在-40～60 ℃之间成像均保持良好，调制传递函数下降5%。

A novel zoom design athermalization (ZDA) method was proposed to realize athermalization for airborne CCD camera rapidly and efficiently. The relational model between athermal design and zoom design was built based on optical passive compensation. First a optical system with good performance was designed to satisfy image quality at normal temperature; and then, multiple zooming positions were established to match different temperature statuses, lastly, by means of optimum design, the proper material combination was achieved rapidly and automatically to satisfy the optical system. A athermal design example for complex airborne CCD camera was designed with 650 mm focal length, F/5.6, 5.5° fieldofview in the 0.450.70 μm waveband by utilizing the ZDA method. The results show that the image quality has a reliable performance with -4060 ℃ temperature range, and the modulation transfer function decreases only by 5%. compared with to the previous approaches, the ZDA method has the advantages of convenience, effectiveness, simplification, and no need for external electromechanical adjustment. These advantages will allow it to be widely applied in many applications, such as airborne optical system, space optical system.
