Patent ID: 7988295

Claim:
An imaging system for optimizing a Diffraction Limited Point Spread Function (DL-PSF) of an imaging light beam, which comprises: a laser unit for generating a laser beam having a substantially plane wavefront; focusing optics for directing the laser beam along a beam path to a focal spot at the fundus of the eye, wherein the focal spot is characterized by a point spread function; an individualized custom phase plate positioned on the beam path to compensate for static optical aberrations introduced into the laser beam by the eye; compensating optics, including the custom phase plate, for altering the laser beam to remove the static aberrations to establish a compensated wavefront for light directed toward the fundus; a wavefront analyzer for continuously measuring a reflected wavefront in real time for light reflected from the fundus; and a computer for comparing the reflected wavefront with the compensated wavefront to obtain an error signal for use in controlling the compensating optics to remove dynamic aberrations from the imaging light beam to minimize the error signal for optimizing the point spread function.
