摘要： Provided is a method and an apparatus for correcting a distortion of a three-dimensional (3D) hologram, in which the method is performed by the apparatus and includes generating a sliced two-dimensional (2D) section of a hologram by slicing the hologram while performing translation in an optical axis direction, obtaining a sharp sliced image of the hologram from a sequence of images of generated sliced 2D sections using a focusing function of a camera, and analyzing a distortion of the obtained sliced image, and using such a method and apparatus may enable correction of a distortion of a 3D hologram independently from a display structure.
