Implementation of an efficient 3D display with high-quality image is beneficiary for a variety of applications, including the entertainment industry, surveillance centers, advanced engineering design, etc. A number of 3D display systems are currently under the development, such as autostereoscopic 3D display (ASD), spatially multiplexed, volumetric and (electro) holographic. Temporally multiplexed ASD approaches have certain advantages as compared to other methods, especially in retaining the full resolution of the display and in providing large headboxes. The confluence of high framerate deformable mirror displays, graphical processing units (GPUs) capable of specialized rendering, high bandwidth commodity grade computer busses (particularly PCI-express) and rapidly switchable, high brightness LEDs have all served to make a high quality temporally multiplexed ASD viable. We report on the incorporation of the previously noted technologies within an ASD with multiple viewing zones and a look around capability. In addition, the same technologies allow for a practical realization of the aspect-in-point display (APD) concept, which couples the use of a temporally multiplexed display in conjunction with the faceted holographic optical elements to form a 3D image. In essence, the APD consists of a multiplex hologram that is electronically updated in a high-speed fashion, incorporating many of the advantages of the former.
