A time‐multiplexed 3d display using steered exit pupils
Source abstract
Abstract
AbstractThis paper presents the multi‐user autostereoscopic 3D display system constructed and operated by the authors using the time‐multiplexing approach. This prototype has three main advantages over the previous versions developed by the authors: its hardware was simplified as only one optical array is used to create viewing regions in space, a lenticular multiplexing screen is not necessary as images can be produced sequentially on a fast 120Hz LCD with full resolution, and the holographic projector was replaced with a high‐frame‐rate digital micromirror device (DMD) projector. The whole system in this prototype consists of four major parts: a 120Hz high‐frame‐rate DMD projector, a 49‐element optical array, a 120Hz screen assembly, and a multi‐user head tracker. The display images for the left/right eyes are produced alternatively on a 120Hz direct‐view LCD and are synchronized with the output of the projector, which acts as a backlight of the LCD. The novel steering optics controlled by the multi‐user head tracker system directs the projector output to regions referred to as exit pupils, which are located in the viewers’ eyes. The display can be developed in the “hang‐on‐the‐wall” form.
