高分辨率空间光学遥感器在轨工作时,由于受到各种因素的影响,无法清晰成像,目前多采用自适应光学方法与技术进行校正。传统自适应光学系统体积较大,结构复杂,难以应用于高分辨率空间光学系统的在轨校正。无波前传感器自适应光学系统去除了传统自适应光学中的波前传感器,大大简化了系统结构,具有体积小、易于实现等优势,特别适用于高分辨率空间光学遥感器的在轨校正。提出了一种利用无波前传感器自适应光学解决高分辨率空间光学遥感器大口径面形误差校正以及宽视场校正等问题的方法。通过对典型的三反射式空间光学遥感器进行仿真研究,验证了利用无波前传感器方法校正大口径主镜面形误差的有效性。搭建了宽视场校正原理性实验平台,通过实验验证了宽视场无波前传感器校正方法的有效性。
High-resolution space optical remote sensor working in orbit, due to a variety of factors, can not be clearly defined, the current use of adaptive optical methods and techniques to correct. The traditional adaptive optics system is bulky and complex in structure, so it is difficult to apply in-orbit correction of high-resolution space optical systems. Wavefront Sensorless Adaptive Optical System removes the wavefront sensor in traditional adaptive optics and greatly simplifies the system structure. It is small in size and easy to implement. It is especially suitable for in-orbit correction of high-resolution space optical remote sensors. A method of adaptive optics without wavefront sensor is proposed to solve the large aperture surface shape error correction and wide field of view correction in high resolution space optical remote sensor. Through the simulation study of a typical three-reflection spatial optical remote sensor, the effectiveness of using the wavefront-free sensor method to correct the large-aperture primary mirror surface shape error is verified. The principle experiment platform of wide field of view correction is set up and the validity of the correction method of wide field of view without wave front sensor is verified by experiments.
