Experimental visual acuity (VA) of eight subjects was measured using the Freiburg vision test in a custom-made adaptive optics system. Measurements were conducted under one control and five defocus-induced conditions. In the defocus-induced conditions, 1 diopter of myopic defocus was added to the system using the Badal stage, and defocus vibrations with five different levels of amplitude were generated by a deformable mirror at 50 Hz. Computational simulations of the visual Strehl ratio (VSOTF) were performed using average aberrations of each subject recorded in the control condition. For the first time, to the best of our knowledge, it has been shown experimentally that both the simulated VSOTF and experimentally measured VA improve when defocus vibrations are added to a defocused eye.
在定制的自适应光学系统中，使用弗莱堡视力测试测量了八名受试者的实验视力（VA）。测量是在一种对照条件和五种散焦诱导条件下进行的。在散焦诱导条件下，使用巴达尔镜台向系统中添加1屈光度的近视性散焦，并且由可变形镜在50Hz下产生具有五种不同幅度水平的散焦振动。使用在对照条件下记录的每个受试者的平均像差进行视觉斯特列尔比率（VSOTF）的计算模拟。据我们所知，首次通过实验表明，当向散焦眼添加散焦振动时，模拟的VSOTF和实验测量的VA都会提高。
