Holographic aberration correction method and apparatus

A holographic aberration correction apparatus comprising:

• a matrix generator configured to generate a plurality of sub-holograms in a hologram, as a matrix;
• a singular value decomposition unit configured to calculate a plurality of eigenmodes and an eigenvalue and a weight corresponding to each of the eigenmodes by performing singular value decomposition on the matrix;
• an eigenmode selector configured to select a predefined number of eigenmodes in the order of largest eigenvalues;
• a calculator configured to calculate 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, and calculate a plurality of second results by performing convolution of the plurality of first results and the plurality of selected eigenmodes respectively;
• and
• a corrector configured to generate an aberration-corrected hologram by adding the plurality of second results.
