A system for precompensating the refractive properties of an eye includes optical components for directing a beam of light through the eye for reflection from the retina. The reflected beam, which includes the refractive aberrations caused by the eye, is then separated into a plurality of individual beams by a lenslet. The plurality of individual beams are then collectively analyzed by a computer to establish an acuity map for the eye. Next, the acuity map is reversed by the computer to generate a negative acuity map, and this negative acuity map is then used to electronically configure the reflective surface of an active mirror in accordance with the negative acuity map. Subsequently, incoming light from a stimulus is reflected from the active mirror, and is thereby precompensated before reaching the eye as an undistorted light beam. It is contemplated by the present invention that a time history of the various active mirror configurations that are required by an eye can be used for diagnostic purposes.

[ What is claimed is:] [1.] A system for precompensating the refractive properties of an eye, the eye having, in order, a cornea, a pupil, a lens and a retina, said system comprising:an optical means for generating a reflection from the retina of the eye;a lenslet array for separating the reflection from the retina into a plurality of individual beams with each said individual beam having a unique optical path length;a computer means for using said plurality of individual beams to create a digitized acuity map of the eye and to generate a signal, said digitized acuity map being indicative of the optical path lengths of said individual beams reflected from the retina, and said signal being indicative of a reverse of said acuity map; andan active mirror, said active mirror being programmed with said signal for precompensating light from a stimulus by reflecting the incoming light from said active mirror to make said optical path lengths of said individual beams appear to be substantially equal to each other.
