Abstract

Digital holography is a powerful technology for a wide range of applications. It combines digital hologram with spatial light modulators (SLMs) and can deliver superior performance which has not been demonstrated before by other technologies. This work proposes a novel method of calculating and optimizing the computer-generated holograms (CGHs) so that a single CGH could be used for white light illumination. The results of this research show that colour dispersion can be reduced by using an iterative algorithm with the aid of a defined perceived image quality, while the shape and sharpness of the target replay fields are maintained.
