随着计算机绘制及光电显示技术的快速发展，封闭式的虚拟现实设备已经不足以满足人们对高临场感体验的追求，混合现实技术因此受到广泛关注。在针对混合现实显示环节的众多解决方案中，光场三维显示可以提供更逼真的显示效果和更直观的用户体验。文中简要比较了实现三维显示的经典技术，并针对光场显示的不同实现方法，讨论了光场三维显示在混合现实中的应用与前景。%With the rapid development of computer rendering and display techniques, it is not enough for the en-closed virtual reality device to satisfy the human’s pursuing to the immersive experience, the mixed reality, as an alternative, has been attracted more attention in recent time. Among the solutions of the display techniques aiming at the mixed reality, light field 3D display is able to provide more vivid display performance and more intuitive human-machine interactive experience. We compare several 3D display methods, and discuss the prospects for the light field display applied to the mixed reality by reviewing different light field display prototypes.
