A method and apparatus for improving the resolution of fundus images and correction of optical aberrations is described in which a bundle of electromagnetic beams is directed into an optical system and the reflected electromagnetic beams are recorded by a sensor. A processor may control the energy source to provide a plurality of different electromagnetic bundles to image the entire optical system. The reflected electromagnetic beams recorded by the sensor are compared to the original electromagnetic bundle configurations to calculate the aberrations of the optical system of interest. Among other applications, the calculated aberrations may be used to construct accurate fundus images, provide input for laser surgery of the eye, fabricate corrective lenses and provide accurate digital images of structures sensed through imperfect optical systems.
