Light field image engine method and apparatus for generating projected 3D light fields

Jukka-Tapani Mäkinen (Inventor), Kai Ojala (Inventor)

Research output: Patent › Patent application

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 mirrors, 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.
