Abstract

A light field head-mounted display (LF-HMD) using a micro structure array (MSA, lens array or pinhole array) is proposed to realize true three dimensional (3D) display. Dense light field of 3D scene is generated inside the exit pupil of HMD and the viewer can obtain correct depth. This method not only solves the huge data problem in true 3D displays, but also alleviates the visual fatigue in traditional HMDs. Design considerations of LF-HMD system have been analyzed in detail and an optical see-through LF-HMD has been designed using a wedge-shaped freeform prism cemented with a freeform lens and a pinhole array. The experimental result shows that the proposed method is capable of generating a dense light field to obtain a corrected perception of depth.
