Abstract
The display of 3D images containing all the depth cues required by the human vision system can be achieved using a reconfigurable Computer Generated Hologram (CGH) with high pixel count. A technique which has been developed to produce CGH's with the required number of pixels, and at video refresh rates, is known as Active TilingTM (AT). At the heart of an AT system is a set of replication optics which produces multiple images of a Spatial Light Modulator (SLM) onto the CGH. The design of two alternative optical systems for geneating a 5x5 tiled array of de-magnified images of a single object is discussed. Results are presented from a 4-channel AT system which has recently been built and demonstrated.
