In this paper, we propose a method to implement a speckleless color dynamic three-dimensional holographic display by modulating amplitude and phase distribution simultaneously. Computer-generated holograms are calculated with an initial uniform phase, and the speckle noise of reconstructed images is suppressed effectively. We perform both numerical simulations and optical experiments to demonstrate the effectiveness of the proposed method. The numerical simulations show that the proposed method can achieve speckleless reconstruction and the optical experiments provide a good color dynamic display effect. It is expected that the proposed method could be widely applied to realize high-quality color dynamic holographic displays in the future.
在本文中，我们提出了一种通过同时调制幅度和相位分布来实现无散斑彩色动态三维全息显示的方法。用初始均匀相位计算计算机生成全息图，有效抑制了重建图像的散斑噪声。我们进行了数值模拟和光学实验来证明所提方法的有效性。数值模拟表明所提方法能够实现无散斑重建，光学实验提供了良好的彩色动态显示效果。预计所提方法未来能够广泛应用于实现高质量彩色动态全息显示。
