Abstract
There is provided an optical element including a light guide, an incoupler, and a beam splitter disposed in an optical path of a display beam between the incoupler and a light engine to generate the display beam. The display beam may comprise first and second beams. The beam splitter may split the display beam to form a first offspring beam including the first beam and a first portion of the second beam, and to form a second offspring beam including a second portion of the second beam. The first and second offspring beams may be incident upon the incoupler at first and second incidence positions respectively. The first incidence position may be different than the second incidence position. The incoupler may direct at least a portion of each of the first and second offspring beams into the light guide to form incoupled first and second offspring beams respectively.
