1. An integrated hologram optical device comprising:
a two-dimensional (2D) array of a plurality of hogels, wherein a holographic element is configured to be recorded on each of the plurality of hogels of the array by adjusting at least one of an angle and a focal length of a signal beam such that a combination of the plurality of hogels of the array operates as an optical element, wherein a lattice plane of each of the plurality of hogels forms an angle with respect to a central axis of the integrated hologram optical device, wherein the angle increases outwardly from the central axis such that the lattice plane of the plurality of hogels farther from the central axis form angles larger than the angles of the lattice plane of the plurality of hogels closer to the central axis, wherein a reflective surface of the lattice plane of each of the plurality of hogels faces the central axis, and wherein the lattice plane is a holographic grating plane on which an interference of the signal beam and a reference beam occurs during the recording.
