Abstract

Light field display is a true three-dimensional (3D) display technology that can produce full depth cues without using any special glasses. A super multi-view display (SMV) technology is one kind of a promising method to realize the light field display, in which a large number of views with an interval smaller than the pupil diameter was produced so that two or more rays passing through one object point in a 3D space enter the pupil simultaneously. Therefore, a viewer could be able to focus on that object point. However, the main bottleneck of its commercialization is the low 3D image resolution with a small field of view, shallow depth, and et. cl. which are limited by the bandwidth of the display devices. To solve this problem, an SMV system with the slanted lenticular lens array attached to a flat panel display was developed in this article. To produce a light field display with a high resolution while maintaining two or three rays entering the pupil, an eye-tracking system is applied. The viewing zone is generated only around the viewer's eyes. The resolution is improved by the reduction of the viewing zone. The crosstalk caused by the manufacture is another issue that affects the 3D image quality. The optical model is developed to simulate the optical characteristics of light field display based on the raytracing considering the fabrication error. The calibration method is proposed to compensate for the error and improve the image quality further.
