Approaches to Non-Glasses-Based 3D Displays

Recent interest in delivering 3D content to the home has been tempered by some reluctance of viewers to wearing stereoscopic selection devices (“glasses”). In addition, the geometry of in-home 3D viewing may enhance accommodation/convergence mismatch of stereoscopic displays that could cause some viewers visual fatigue. Both of these issues motivate the desire for “non-glasses-based” 3D (NG3D) displays, also known as “autostereoscopic” displays. This paper will address the general theory of the light field, a function that describes the amount of light traveling in every direction through every point in space. It will then discus how this light field could be generated to allow for NG3D displays. These mechanisms include integral photography, lenticular displays, parallax barriers, computer generated holography (CGH), and time multiplexed image steering.
