摘要：
A design method is presented for computing the transmittance of computer-generated holograms dedicated to geometric transformations. The procedure is based on an iterative Fourier transform algorithm and allows both the quantization of the hologram levels and the accuracy of the transformed output to be taken into account, Computer simulations and experimental results are presented, confirming this flexible design approach.
