Autostereoscopic, Partial Pixel, Spatially Multiplexed, and other 3D Display Technologies

Abstract

The technologies and advances in the field of three-dimensional (3D)displayswithin the past two decades are reviewed. Specifically, the developmentsindiffractive, refractive, reflective and occlusive 3D display strategiesarediscussed, highlighting the advantages and limitations of the associatedsystems. The partial pixel and the partial object pixel architecturesassociatedwith autostereoscopic displays are discussed in some detail, whileothertechniques are briefly introduced. It is shown that major breakthroughsoccurred with the development of computer-generated holography (CGH),liquid crystal arrays (LCA) and other spatial light modulators (SLM),and alsothe discrete fabrication of diffractive and holographic optical elements(DOEand HOE), micromirror arrays, and microelectromechanical systems (MEMS).These techniques and components have enabled the implementation ofspatiallyand angularly multiplexed 3D images and scenes with potentially dynamic(time-varying) features
