Abstract: Dual-view integral imaging (DVⅡ) three-dimensional (3D) display presents two different 3D images in the left and right viewing directions, respectively. However, the low resolution limits the applications of the DVⅡ 3D display. This paper proposes a one-dimensional DVⅡ 3D display based on a parallax barrier. The element image array is composed of two sets of alternating elemental images. The two sets of elemental images are captured from two different 3D scenes, respectively. The mathematical relation between the pitches of elemental image and slit is deduced through geometrical optics. According to the width of the 3D viewing zone, the calculation formula of the viewing angle is obtained. The mathematical relation between the optimal viewing distance and the parameters of the one-dimensional DVⅡ 3D display is also analyzed. A prototype of the one-dimensional DVⅡ 3D display based on the parallax barrier is developed to verify the principle. The 3D scene "CS" is obtained between 18° and 2° to the left, while the 3D scene 'SC' is seen between 2° and 18° to the right.
