FIELD: physics.SUBSTANCE: method includes using a correcting holographic optical element in the form of a digital hologram; positioning a CCD array behind the paraxial image plane of the object; recording the defocused image constructed by the lens, said image being taken as the digital axial hologram of the image with which, using digital holography techniques, holographic fragments of the entire image are reconstructed numerically and layer-by-layer, after which the reconstructed image fragments are transferred to a single plane.EFFECT: wider field of use, faster operation and quality of holographic correction of lens aberrations.10 dwg |
