Abstract

A novel adaptive optics vision simulator (AOVS) is presented and characterized for several design features, including automated measuring and compensating eye’s aberrations up to the fifth order, which fully cover aberrations typically found in the human eye, even for the cases of highly aberrated eyes. Especially, it is equipped with 35 elements bimorph deformable mirror with bigger stroke and smaller size, which could help establish near-diffraction-limited ocular optics condition. To investigate the validity of this apparatus, pilot data under different aberration correction pattern from one subjects are collected, and contrast sensitivity function (CSF), an important psychophysical function in vision, is obtained also. Results from living eyes show a practically perfect aberration correction and demonstrate the utility of this system.
