The aberrations are synthesized by arranging three computer-generated holograms (CGHs) in serial geometry which generate coma, astismatism and spherical aberration, respectively. The diffraction patterns suffering form third-order combined aberration are reconstructed and compared with the numerical ones. There is good agreement between experimental and theoretical results. The relation between the maximum amount of aberration to be reconstructed and the required sample number of CGH is discussed.
