Hologram generation using light-field modulated zone plates

A hologram calculation technique is proposed in this study using a depth image and light-field information comprising multiple parallax images. The depth image is used to determine the phase distribution of the zone plates, and the amplitude distribution is modulated using the light-field information. An object wave of three-dimensional (3D) objects is obtained by adding the light-field modulated zone plates. The proposed technique can generate sharp and shaded 3D images in space. The occlusion effects of 3D images can also be supported by modifying the amplitude modulation scheme. The proposed technique was experimentally verified.
