Rapid, Automatic Measurement of the Eye's Wave Aberration

Brief Description
A process for computing the aberrations of the eye in real time from wavefront measurements using a wavefront sensor such as  a Hartmann-Shack detector.

Applications
Real-time determination of the aberrations of the living human eye is necessary for high resolution imaging of the retina for diagnostic evaluation.  This is necessary because the eye is constantly moving.

Advantages
The aberrations of the eye can be determined at rates as high as 60 times a second.   The algorithms can be run on a simple computer processor.  Aberrations for different pupil sizes are handled for data taken on a single pupil size by renormalization.
