video reproduced by other techniques [88] [92]. Some of the proposed display techniques
using holography are detailed in [93-95]. The advantage of this technique is that it cap-
tures the true 3D wavefront of a scene and the retention of motion parallax. However,
due to the demand for high resolution recording medium and replay medium, this display
technique is difficult to implement for natural scenes with acceptable image resolutions
with the existing technologies. For instance, a large display of say 100 mm diagonal will

aSpatialLightModulator(SLM)tobemanufacturedwithsufficientpixelresolution [88].
Nonetheless, holographic display technique can be deployed in reduced parallax systems
(e.g. stereo-holography or lenticular), which reduce the demand for high-end technolo-
gies.
