A method for improving the spectral distribution and for reducing
the reconstruction error in optical holographic data storage is
proposed. By use of an optimized phase mask in the input plane, the
uniformity of the spectral distribution is optimized and the
reconstruction error minimized. The phase mask is designed by use
of amplitude-phase retrieval algorithms. Simulation results show
the merits of the proposed method.
