Abstract
Laser Doppler holography is a technique developed to visualize blood vessels in human eye fundus and its dynamics. Quality of images obtained is compromised due to aberrations introduced by the anterior segment of the eye as well as by lenses used for viewing. As images calculated hold information about both amplitude and the phase of the field detected, the wavefront distortion can be estimated using the numerical Shack-Hartmann method in the off-line video rendering process. In result, resolution of images obtained is considerably increased and smaller blood vessels are revealed.
