Abstract
This paper describes a multi-view stereoscopic 3-D display. The display technology does not involve goggles, polarized glasses, colored glasses or any other eyewear. It allows parallax, in that as the viewer moves their head left and right, the viewer can 'see around corners.' The method involves a microlens array on top of a liquid crystal display. The microlens is designed to project multiple views to multiple eye positions. The distance between stereo eye positions is the average distance between eyes of 55 mm. As many as eight views are interlaced on the display and fanned out by the microlens array. Thus 4 stereo pairs can be observed, each pair from a unique angular perspective. For this system, since multiple views are available, seeing the 3-D effect is much easier. In addition, the 3-D effect can be seen far off axis; so more than 1 person can view the display at the same time.
