Holographic techniques offer a route to the generation of 3-D images having all the depth cues used by the human vision system. Reconfigurable computer generated holograms allow interactive display of computer held data and synthetic objects. The available number of pixels within the computer generated hologram (CGH) constrains the image size and field of view of such holograms and up to 1012 pixels are required to generate full parallax images having widths of -5OO mm and a field of view of This has significant implications on both the computation and electro-optic replay of CGH images. To fmd practical applications, such CGH display systems require electro-optic modulators which deliver a spatial band width product (SBWP) significantly higher than currently available electro-optic modulator or display solutions.A new electro-optic modulator system has been developed by the authors to replay dynamic holographic images. This Active TilingTM system offers a route to replay giga-pixel CGH images with video refresh rates. High speed, medium complexity electrically addressed spatial light modulators are combined with a high resolution optically addressed spatial light modulator to provide ultra-high complexity, video frame rate holographic data suitable for coherent readout.
