Abstract

In this Letter, we introduce a computer-generated hologram (CGH) optimization method to enhance the depth cue based on complex amplitude modulation (CAM). An iterative algorithm is designed to generate the optimized random phase (ORAP) according to the size of the target image and the bandwidth limitation condition. The ORAP with limited bandwidth is used as the initial phase of the target image and the hologram is encoded based on the analytical formula. Our proposal can maintain the advantages of CAM and achieve holographic three-dimensional (3D) display with an enhanced depth cue. It is expected that the proposed method could be widely used in holographic field in the future.
