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.
