Abstract

Spatial-light-modulators (SLM) are increasingly used as active elements in adaptive optics (AO) systems to simulate optical corrections, in particular multifocal presbyopic corrections. In this study, we compared vision with lathe-manufactured multi-zone (2-4) multifocal, angularly and radially, segmented surfaces and through the same corrections simulated with a SLM in a custom-developed two-active-element AO visual simulator. We found that perceived visual quality measured through real manufactured surfaces and SLM-simulated phase maps corresponded highly. Optical simulations predicted differences in perceived visual quality across different designs at Far distance, but showed some discrepancies at intermediate and near.

摘要

空间光调制器(SLM)越来越多地被用作自适应光学(AO)系统中的有源元件,以模拟光学矫正,特别是多焦点老视矫正。在本研究中,我们在一个定制开发的双有源元件AO视觉模拟器中,比较了使用车床制造的多区域(2 - 4个)多焦点、角度和径向分段表面的视觉效果,以及通过空间光调制器模拟相同矫正后的视觉效果。我们发现,通过实际制造的表面和空间光调制器模拟的相位图测量得到的感知视觉质量高度一致。光学模拟预测了不同设计在远距离时感知视觉质量的差异,但在中距离和近距离时显示出一些差异。
