    摘要： The specification and drawings present a new apparatus and method for using exit pupil expanders (EPE) with spherical or aspheric non-flat substrates and a plurality of diffractive elements for expanding the exit pupil of a display for viewing in order to reduce image spreading. This can also enable improved image resolution and utilization of shorter focus distances.

    摘要： An apparatus and a method are provided. The apparatus comprises: a light expander configured to expand light, input into the light expander, in a first dimension, and configured to provide diverging light that diverges in the first dimension; and an optical device configured to redirect diverging light, received from the light expander, to produce converging light that converges in the first dimension.
