Abstract

An eye simulation system for testing wavefront sensor systems, the eye stimulation system comprising a housing having a chamber with an opening for allowing light to enter said chamber, a fluid located in the chamber, said fluid having a known index of refraction, a lens positioned relative to said housing such that light entering the opening of the chamber passes through said lens, and a rotatable imaging surface positioned in said chamber such that light passing through said lens propagates through said fluid and is incident on said rotatable imaging surface.
