Paper Abstract

A focus-tunable multi-view holographic three-dimensional (3D) display system with a 10.1 inch 4K liquid crystal device (LCD) panel is presented. In the proposed synthesizing method, computer-generated hologram (CGH) does not require calculations of light diffraction. When multiple rays pass through one point of a 3D image and enter the pupil simultaneously, the eyes can focus on the point according to the depth cue. Benefiting from the holograms, the dense multiple perspective viewpoints of the 3D object are recorded and combined into the CGH in a dense-super-view way, which make two or more rays emitted from the same point in reconstructed light field into the pupil simultaneously. In general, a wavefront is converged to a viewpoint with the amplitude distribution of multi-view images on the hologram plane, and the phase distribution of a spherical wave is converged to the viewpoint. Here, the wavefronts are calculated according to all the multi-view images and then they are summed up to obtain the object wave on the hologram plane. Moreover, the reference light (converging light) is adopted to converge the central diffraction wave from the liquid crystal display (LCD) into a common area in a short view distance. Experimental results shows that the proposed holographic display can regenerate the 3D objects with focus cues: accommodation and retinal blur.
