1. A light-field generating device displaying a near-eye light field and comprising:
a display panel divided into a plurality of sub-areas, wherein said sub-areas display light-field subsets simultaneously and wherein each of said light field subsets corresponds to a different field angle;
a projecting lens-array unit, wherein the light rays of a plurality of different scenes are emitted to a common diaphragm from said sub-areas of said display panel and collimated by said projecting lens-array;
a fusion lens unit, wherein the light rays emitted from said projecting lens-array unit are focused on an imaging plane to form a real image; and
an eyepiece unit, wherein the light rays forming said real image are collimated, and wherein the eyepiece unit includes a beam splitter or a prism with a multiple spectrum coating.
