Error diffusion has been proven to be a valuable tool in the calculation of computer-generated holograms. Real-valued error diffusion has been used to calculate the transmission functions for real-valued holograms with off-axis reconstructions. We demonstrate the use of a complex-valued error-diffusion algorithm on real-valued hologram data in order to achieve larger flexibility in the shaping of the noise spectrum.
