Paper Abstract

We have developed a hybrid adaptive optics visual simulator, combining two different phase manipulation technologies: an optically-addressed liquid crystal phase modulator, with a relatively slow temporal response but capable of producing abrupt or discontinuous phase profiles with high fidelity; and a membrane deformable mirror, restricted to smooth profiles but with a temporal response allowing close-loop compensation of the eye's aberration fluctuations. As proof of concept, objective results as a function of defocus are presented for a phase element structured as discontinuous radial sectors, generated with the liquid crystal modulator while the deformable mirror was used to correct the system aberrations and, further, to introduce the aberrations of two real subjects. The hybrid adaptive optics visual simulator is specially intended as a tool for developing new ophthalmic optics elements, where it opens the possibility to explore designs with irregularities and/or discontinuities.
