| 摘 要： | 卫星发射时的振动、由空气到真空环境的转变、微重力的影响等因素都可能会改变相机的焦面位置，导致相机焦面位置发生变化。CBERS-02B卫星在轨测试期间，对高分辨率相机进行了在轨调焦，并取得了明显效果。文章对高分辨率相机的在轨调焦方法和调焦结果进行介绍。

| Abstract: | Vibration during the launch and transition from air to vacuum may defocus the camera and degrade the image quality.During the China Brazil Earth Resource Satellite's testing period,a successful in-flight refocusing experiment of high-resolution camera had been done,which greatly improved the image quality.The paper briefly introduced the in-flight refocusing method and result. |
