[0047] Best Mode for Carrying Out the Invention
[0048] The basic principle of the computer-synthesized hologram of the present invention is, in order to eliminate the pixel structure on the hologram surface, on the position away from the hologram surface, define a lot of its emission brightness different because of different emission directions, have the same direction as the object surface. the virtual point light sources whose emission brightness is the same as that on the surface of the object, whose emission brightness is different due to the different focusing directions, and which have the same emission brightness as that on the surface of the object; to emit from these virtual point light sources The light or the light converging on these virtual focusing points is used as virtual object light to make a computer-synthesized hologram, so as to make a high-resolution computer-synthesized hologram (CGH) without holography.
