Abstract

A frontal multi-projection (FMP) autostereoscopic display using a 3D-image-guided screen is proposed for improving space efficiency. Based on the optical multiplexing and de-multiplexing, the important optical functions of 3D-image-guided screen are parallax image interlacing and view-separating, which is capable of reconstructing 3D images without quality degradation from the front direction. The operating principle, optical design calculation equations and correction method of parallax images are described in detail. A 50-inch FMP autostereoscopic prototype based on the 3D-guided-image screen with pixels $({{1024}}\times {{768}}\times {{8}})$ is developed, which enhances the brightness and 3D perceptions. The performance of this prototype is evaluated by measuring the luminance and crosstalk distribution along the horizontal direction at the optimum viewing distance. This research has potential applications in some commercial entertainments and movies for the realistic 3D perceptions.
