In this paper, we propose a dual-view integral imaging (DVII) three-dimensional (3D) display that presents different 3D images in the left and right viewing directions simultaneously. The DVII 3D display consists of a display panel and a microlens array, and its elemental image array (EIA) is composed of two sub-EIAs. The sub-EIAs captured for two different 3D scenes are responsible for two different 3D images in the left-view and right-view integral imaging 3D displays, respectively. A prototype of the DVII 3D display using a pinhole array is developed, and good results are obtained.

Abstract:In this paper, we analyze the depth of field (DOF) of integral imaging displays based on wave optics. With considering the diffraction effect, we analyze the intensity distribution of light with multiple microlenses and derive a DOF calculation formula for integral imaging display system. We study the variations of DOF values with different system parameters. Experimental results are provided to verify the accuracy of the theoretical analysis. The analyses and experimental results presented in this paper could be beneficial for better understanding and designing of integral imaging displays. References and links1. G.

We propose a dual-view integral imaging (DVII) 3D display using polarizer parallax barriers (PPBs). The DVII 3D display consists of a display panel, a microlens array, and two PPBs. The elemental images (EIs) displayed on the left and right half of the display panel are captured from two different 3D scenes, respectively. The lights emitted from two kinds of EIs are modulated by the left and right half of the microlens array to present two different 3D images, respectively. A prototype of the DVII 3D display is developed, and the experimental results agree well with the theory.

Two of the main limitations of integral imaging are the crosstalk and the narrow viewing angle. In this paper, a crosstalk free integral imaging display with wide viewing angle is proposed. A layer of transparent high refractive index packing medium is padded onto a display panel to enhance the viewing angle, and then a periodic black mask is coated on the top surface of the medium layer to avoid the crosstalk and image flipping. The proposed integral imaging display can provide us with crosstalk free 3D images within a wide viewing angle. Experiments are carried out and good results finally verify the feasibility of the proposed method.Index Terms-3D display, crosstalk, integral imaging (II), viewing angle, viewing zone.

In this paper, we propose a concept of the optimal viewing distance range and a depth calculation method of integral imaging. By considering the light emanating from a single elemental image point as a Gaussian beam, we analyze the integral imaging depth range and deduce the depth calculation formulas in different display modes. Experiments in focused mode were carried out, and good results finally confirmed the feasibility of the proposed method.Index Terms-Depth of field, Gaussian beam, integral imaging, viewing distance, 3D display.

In this paper, we propose a tilted elemental image array generation method for computer generated integral imaging display with reduced moiré patterns. The pixels of the tilted elemental image array are divided into border pixels and effective pixels. According to the optimal tilted angle, the effective pixels are arranged with uniform arrangement. Also, a pixel mapping method is proposed. Appropriate experiments are carried out and the experimental results show that not only the color moiré patterns are reduced remarkably, but also the resolution of the reconstructed 3D images are improved through the proposed method.
