【摘要】：如何有效矫正随人群起伏很大的人眼像差,提高人眼自适应光学系统的人群适用范围是临床应用面临的最大难题。旋转双柱面镜散光补偿技术是一种使用灵活、低成本的散光补偿方法。给出了旋转双柱面镜散光矫正的理论依据,并搭建了基于远场光斑形态的散光自动补偿实验系统,验证了旋转双柱面镜散光矫正理论的正确性。在此基础上,将旋转双柱面镜与人眼自适应光学系统相结合,利用哈特曼波前测量数据调整双柱面镜,实现了(-4~0D_c)散光的全自动补偿,补偿精度优于0.1 D_c,并验证了实际人眼散光补偿效果。该技术结合Badal调焦可以为人眼自适应光学系统的大规模人群适用提供一种经济有效的低阶像差补偿方案。
[Abstract]:How to effectively correct the human eye aberration which fluctuates greatly with the crowd and how to improve the population applicable range of the human eye adaptive optics system is the biggest problem in clinical application. Rotating double cylinder mirror astigmatism compensation technology is a flexible, low-cost astigmatism compensation method. The theoretical basis of astigmatism correction for rotating double-cylinder mirror is given, and an experimental system for automatic compensation of astigmatism based on far-field spot morphology is set up, which verifies the correctness of the theory of astigmatism correction for rotating double-cylindrical mirror. On this basis, the rotating double-cylinder mirror is combined with the human eye adaptive optical system, and the dual-cylinder mirror is adjusted by using the Hartmann wave front measurement data. The automatic compensation of (- 4~0D_c) astigmatism is realized, and the compensation accuracy is better than 0.1 DC. The effect of astigmatism compensation is verified. This technique combined with Badal focusing can provide an economical and effective low order aberration compensation scheme for the large population of human eye adaptive optical system.
