| description | The invention relates to a space camera, in particular to a large-focal-depth space camera and an imaging method thereof, solves the problem that a high-quality clear optical image of a space target is difficult to obtain through an existing method, utilizes a variable-curvature reflecting mirror as a secondary mirror, and rapidly adjusts the curvature radius of the secondary mirror within the integral time of a detector, so that the high-quality clear optical image of the space target is obtained. And scanning and focusing an object space, superposing distance change information in an intermediate image in a modulation coding mode, and recovering the intermediate coded image through decoding and filtering to realize clear imaging. The focusing-free design provides a new thought for the space camera to clearly image a space target with an unknown imaging distance and fast distance change.
本发明涉及一种空间相机，具体涉及一种大焦深空间相机及其成像方法，克服通过现有方法难以获取高质量的空间目标清晰光学图像的问题，利用变曲率反射镜作为次镜，通过在探测器积分时间内，快速调节次镜的曲率半径，对物方空间进行扫描聚焦并将距离变化信息以调制编 |
