Abstract
Systems and methods are described for providing a three-dimensional display. In an example, a display device includes a light engine, a spatial light modulator, one or more directable minors, and a projection lens. Light from the light engine is modulated by the spatial light modulator, reflected by the directable mirror(s) toward the projection lens, and projected by the projection lens (e.g. onto a screen). The directable mirror(s) may include a rotatable mirror or a digital micromirror device. The spatial light modulator may be a digital micromirror device. The spatial light modulator and the directable mirror(s) are synchronized so as to generate different modulated light patterns for different positions of the directable mirror(s). The projection of different modulated light patterns in different directions may generate different views that are visible from different user perspectives.
