Holographic true 3D displays attempt to duplicate the original light field with all its relevant physical features. To this end, spatial light modulators (SLM) are commonly used as display devices. Currently available SLMs do not satisfy the technical specifications to achieve a
consumer quality true 3D display; one of the important drawbacks is the rather large pixel size, and this results in a low spatial resolution of the fringe pattern written on the SLM which in turn severely restricts the diffraction/viewing angle. A design that uses low spatial resolution,
but still achieves a 360-degrees viewing angle, using a parabolic mirror was already reported. Here in this design, the parabolic mirror is replaced by a Fresnel phase plate which is mounted as a covering layer on top of the SLM.
