1. A holographic aberration correction method comprising:
generating a plurality of sub-holograms in a hologram, as a matrix;
calculating a plurality of eigenmodes and an eigenvalue and a weight corresponding to each of the eigenmodes by performing singular value decomposition on the matrix;
selecting a predefined number of eigenmodes in the order of largest eigenvalues;
calculating a plurality of first results which are obtained by multiplying a plurality of identical images by respective weights corresponding to the plurality of selected eigenmodes;
calculating a plurality of second results by performing convolution of the plurality of first results with the plurality of selected eigenmodes, respectively; and
generating an aberration-corrected hologram by adding the plurality of second results.
