Title: Design methods to generate a computer hologram for improving image quality
Abstract: In order to suppress the speckle noise on a holographic display, we propose two design methods to initialize the phase to generate a computer hologram illuminating with partially coherent light. We introduce an initial phase of the image in consideration of the relationship of gray value among adjacent pixels when generating the computer hologram. After simulations, we compare these two methods and conclude that one is better than the other in terms of running speed or quality of the reconstructed image. Finally, we perform experiments to verify the theory. It is expected that these methods can greatly enhance the quality of reconstructed images and could be widely applied in the holographic field in the future.
