Estimating the term…
A 3D projection display comprises an autostereoscopic image producing unit which directs light beams corresponding to respective 2D views in different directions towards a projection lens. The projection lens co-operates with the image producing unit to image the light beams at respective different regions in the aperture of the projection lens. A light-transmissive screen co-operates with the image producing unit and the projection lens to image the views at the screen. The screen may comprise a Fresnel lens, or where a magnified image of increased angular spread is required, a double lenticular screen angular amplifier.
A three-dimensional projection display apparatus, comprising autostereoscopic image producing means for directing light beams corresponding to respective views in different directions, further comprising at least one projection lens co-operating with the autostereoscopic image producing means to image the light beams at respective different regions in the aperture of the projection lens, and a light-transmissive or light-reflective screen co-operating with the autostereoscopic image producing means and the projection lens to image the views at the screen.
