Abstract

We describe the optical design of a confocal scanning laser ophthalmoscope with two deformable mirrors. Spherical mirrors are used for pupil relay. Defocus aberration of the human eye is corrected by a Badal focusing structure and astigmatism aberration is corrected by a deformable mirror. The main optical system achieves a diffraction-limited performance through the entire scanning field (6 mm pupil, 3 degrees on pupil plane). The performance of the optical system, with correction of defocus and astigmatism, is also evaluated.

摘要

我们描述了一种带有两个可变形镜的共焦扫描激光眼科显微镜的光学设计。球面镜用于瞳孔中继。人眼的离焦像差通过巴达尔聚焦结构校正，散光像差通过可变形镜校正。主光学系统在整个扫描场（6毫米瞳孔，瞳孔平面上3度）实现了衍射极限性能。还评估了校正离焦和散光后的光学系统性能。
