A device and method for aberration-free imaging of the fundus of the human eye includes a light source, an active mirror for directing light from the light source to and from the fundus and imaging units for viewing the fundus. A sensor compares the wavefront reflected from the eye with an aberration-free wavefront to establish an error signal, and the error signal is used to program the active mirror to remove aberrations from the reflected light. Importantly, all of this is done by focusing the light to a focal spot on the fundus which has three dimensional volumetric measurements, i.e. point spread function (PSF), of as small as approximately 2 mumx2 mumx20 mum. The imaging units include an ellipsometer and a fluoroscope, and the light source can be a laser diode or an AP-diode.
