Abstract
A convex multi-projector light-field display system includes projectors and a convex diffusion screen facing the projectors. The convex diffusion screen and the plurality of projectors share a same center of curvature, such that each projector projects the image at normal incidence to the convex diffusion screen. Projections of the projectors overlap in an optimal viewing area, within which an observer sees images projected by the projectors, and the optimal viewing area and the plurality of projectors are disposed on opposite sides of the convex diffusion screen.
