Abstract

An optimum background correction method based on the Gerchberg-Saxton (GS) algorithm is proposed to improve the beam shaping effect of a computer-generated hologram. The zero-value pixels of a black-white image which is used as the target optical field in a beam shaping process is replaced with an optimum background correction value obtained from a fitting function, which has been deduced from simulations in advance and can be generally applied for the calculation of the optimum value for the target optical field. The simulation results show that the root-mean square error of the reconstructed field obtained by the proposed method can be much lower than that obtained directly by the GS algorithm.
