Patent ID: 7768684

Claim:
A method, comprising: sampling complex spatial frequency values derived from a curved mathematical wavefront over a plurality of points across a hogel of a spatial light modulator (SLM) panel comprising a plurality of hogels, where the curved mathematical wavefront is notionally transmitted from a point in an image volume through an optical system to the hogel and wherein the curved mathematical wavefront is modeled to include predetermined image distortion associated with the optical system; calculating hogel vectors from both the sampled spatial frequency values and from stored geometric data representing a three-dimensional object to be displayed as holographic image in the image volume, wherein the hogel vectors are used to produce a diffraction pattern; writing the diffraction pattern to the SLM panel; illuminating the SLM panel with light; and diffracting the light to generate an optical curved wavefront associated with the hogel vectors, wherein the optical curved wavefront comprises an inverse distortion of the optical system, and wherein the optical curved wavefront produces a point of the holographic image in the image volume.
