摘要
提出了一种基于21单元变形镜与全息波前传感器的全息自适应光学系统,并对其像差校正能力进行了分析.首先描述了全息波前传感器基本原理,并在薄全息图近似下给出基于快速傅里叶变换算法的全息波前传感器数值模型;然后基于21单元变形镜的数值模型,分析了该变形镜的波前校正能力;在此基础上,数值模拟并实验验证了全息自适应光学系统对静态像差的闭环校正能力.
We propose a holographic adaptive optics system based on holographic wavefront sensor and 21-element deformable mirror, and analyze the wavefront correction ability of the system in this paper. The principle of holographic wavefront sensor is described, and its numerical model is provided by fast Fourier transform algorithm in the thin hologram approximation. Then, the wavefront correction ability of 21-element deformable mirror is analyzed with its numerical model. Finally, the aberration compensation of the system is simulated and an experimental device is set up to verify the feasibility of the proposed adaptive optics system.
