Abstract
The present disclosure relates to systems and methods for projecting a light field. One light field projection system includes a screen and a projection unit. On the screen, there is a plurality of convex reflective elements arranged in a two-dimensional array. The projection unit has a light source. The projection unit also has a modulator to modulate light from the light source. The projection unit further has one or more movable mirrored elements to reflect light from the light source toward the screen to sequentially scan the plurality of convex reflective elements. The projection unit also has a control system that determines a light modulation scheme used by the modulator. The light modulation scheme provides that the light reflected from the light source toward the screen to sequentially scan the plurality of convex reflective elements forms a light field that is concurrently viewable from a plurality of perspectives.
