| 摘 要： | 利用20单元双压电片变形镜和13×13阵列哈特曼波前传感器所构成的闭环自适应光学系统,实验测试了双压电片变形镜对3～20项静态Zernike像差的空间校正能力,并将实验结果与仿真计算结果进行了对比.最后分析了哈特曼传感器与双压电片变形镜之间的对准误差对实验结果的影响.研究表明,除了少数几项外,双压电片变形镜对3～20项Zernike像差的拟合误差都小于0.5,各项Zernike仿真和实验结果之差平均小于0.1.计算表明,与严格对准的理想情况相比,双压电片变形镜对3～20项Zernike像差中大多数项的拟合误差都随着失配程度的增加而增大,对准精度对于高阶像差拟合效果的影响尤其严重.

| Abstract: | A closed-loop adaptive optics system, which consists of a 20-element bimorph deformable mirror and a Shack-Hartmann wave-front sensor with 13?3 sub-aperture arrays, is established to test the spatial fitting capability to 3 ?20 Zernike items of the bimorph deformable mirror. Constrast is made between experimental result and simulation result. And the effect of mismatch between bimorph deformable mirror and the sub-apertures of Shack- Hartmann sensor is analyzed. Results show that most of the fitting errors ... |
