Projection-type dual-view three-dimensional display system based on integral imaging

Abstract

A dual-view display system provides two different images in different directions. Most of them only present two-dimensional images for observers. In this paper, we propose a projection-type dual-view three-dimensional (3D) display system based on integral imaging. To assign directivities to the images, a projection-type display and dual-view screen with lenticular lenses are implemented. The lenticular lenses split the collimated image from the projection device into two different directions. The separated images are integrated by a single lens array in front of the screen, and full-parallax 3D images are observed in two different viewing regions. The visibility of the reconstructed 3D images can be improved by using high-density lenticular lenses and a high numerical aperture lens array. We explain the principle of the proposed method and verify the feasibility of the proposed system with simulations and experimental results.

Dual-View Integral Imaging 3D Display Based on Multiplexed Lens-Array Holographic Optical Element

“…In order to increase the viewing angle of the dual-view 3D display, we proposed a dual-view integral imaging 3D display using polarizer parallax barriers [17], but the resolution of each 3D image is reduced to half of the conventional one. In order to solve these issues, Seoul University proposed a projection-type dual-view 3D display based on integral imaging [19], but the display system is bulky. Then we proposed a dual-view integral imaging 3D display using an orthogonal polarizer array and polarization switcher [18], but the brightness is not high.…”

Dual-View Three-Dimensional Display Based on Direct-Projection Integral Imaging with Convex Mirror Arrays

“…As an alternative, an integral imaging-based DV 3-D display was proposed [20][21][22][23]. Wu and et al suggested a DV 3-D LCD system based on the lens array-based off-axis integral imaging method [19].…”

“…In fact, for the practical application of the 3-D DV display, two viewing-zones must be completely separated and have relatively large viewing-angles to experience the perspective changes of 3-D images. For this, J. Jeong et al proposed a projection-type DV 3-D display based on integral imaging [23]. They used a series of optical elements, such as a collimator, a lenticular lens with a vertical diffuser, and convex lens array for generation of a collimated beam, separation of DV images with enhanced viewing-angles, and integration of 3-D images to be displayed in their viewing zones, respectively.…”

“…The scale of this system may also depend on the practical sizes of the lenticular lens and collimator. Furthermore, this convex-lens-array-based projection integral imaging (CLA-PII) system shows a narrower viewing angle than the of the convex-mirror-array-based system [23].…”

P‐86: Multi‐view‐zone 3D Display System Based on Integral Imaging

“…In the second method, the elemental images are displayed on the left and right half of the display panel, but the 3D resolution of each 3D image is by half [12]. In the third method, the orthogonal polarizer arrays and the polarization switcher are used, the viewing zones and 3D resolution are the same as the conventional II 3D display, but it reduces the brightness and resolutionof the 3D images [13].In order to solve the above shortcomings,Seoul University has put forward a method [14].The lenticular lenses split the collimated image from the projection device into two different directions, although the reconstructed 3D images have high brightness, but the imaging quality has serious crosstalk, and the imaging quality is not good.…”
