Analysis of two novel concepts for multiview three-dimensional displays using one projector

We present two concepts to create multiview 3-D displays with high spatial and angular resolution at a reasonable system cost. We investigate a rear projection approach using only one projector with a digital micromirror device as a light modulator. The first concept is based on time sequentially illuminating the entire light modulator from different directions. Each illumination direction corresponds to a different viewing zone. We design an illumination system that generates all distinct illumination beams, and a lens system integrated into the projection screen to enlarge the viewing zones. A second concept is based on a projection screen architecture that steers images into different horizontal directions and does not require a directional illumination of the light modulator. In this way, the entire acceptance etendue of the projection system can be used for every image. This is achieved by horizontally moving a double-sided lenticular sheet with respect to a sheet of microlenses with a square footprint. Both concepts are investigated with advanced optical simulations. (C) 2010 Society of Photo-Optical Instrumentation Engineers. [DOI: 10.1117/1.3524240]
