Adaptive system for eye-fundus imaging

Adaptive system for eye-fundus imaging

A compact adaptive system capable of imaging a human-eye retina with a spatial resolution as high as 6 {mu}m and a field of view of 15{sup 0} is developed. It is shown that a modal bimorph corrector with nonlocalised response functions provides the efficient suppression of dynamic aberrations of a h...

Zusammenfassung:A compact adaptive system capable of imaging a human-eye retina with a spatial resolution as high as 6 {mu}m and a field of view of 15{sup 0} is developed. It is shown that a modal bimorph corrector with nonlocalised response functions provides the efficient suppression of dynamic aberrations of a human eye. The residual root-mean-square error in correction of aberrations of a real eye with nonparalysed accommodation lies in the range of 0.1 - 0.15 {mu}m.
