Abstract:
A device for aberration-free imaging of the fundus of the human eye which comprises:a plurality of imaging units; an active mirror; a light source for generating an incident light beam, said incident light beam having an incident wavefront; an optical element for focusing said incident light beam to a focal spot in the fundus for reflection therefrom as a reflected beam; a sensor for determining a reflected wavefront, said reflected wavefront being characteristic of said reflected beam; a comparator for comparing said reflected wavefront with an aberration-free wavefront to establish an error signal; and a means for programming said active mirror with said error signal to compensate said incident wavefront for focus by said optical element as an aberration-free wavefront to said focal spot in the fundus, and to compensate said reflected wavefront for receipt by said imaging units as an aberration-free wavefront.
