Abstract

We propose a new multicriteria method for the determination of computer-generated holograms (CGH’s). For this purpose, the direct binary search (DBS) algorithm for computing CGH’s has been modified to converge on a new error function that defines the optimal trade-off among different criteria. This approach allows us to control the trade-off between the amplitude error and the diffraction efficiency and to provide a rigorous figure of merit. Comparisons among different encoding methods show that the best results are obtained with a modified version of the DBS method combined with the iterative Fourier transform algorithm.
