Verification of computer display pre-compensation for visual aberrations in an artificial eye

The possibility of pre-compensating images in a computer display according to the visual aberrations previously assessed in an optical system (e.g., the computer user’s eye) has been confirmed for a simple “artificial eye”. This device has been constructed from optical components, which include a plano-convex lens, an adjustable aperture, and a Charged-Couple Device (CCD) array that mimics the retina of a real eye. While the CCD array allows for the inspection of the image as it would form on the retina of a real eye, its specular reflection does not allow the resulting “artificial eye” to be measured appropriately in a wavefront analyzer (a necessary pre-requisite for the image precompensation process). Therefore, an alternative, interchangeable CCD array covered with gray paint (i.e., disabled) was also created to provide the diffuse reflectivity that is presumed in the operation of the wavefront analyzer. Experiments with this system show that the visual aberrations in a ...
