Abstract
An example apparatus for a beam guiding device. The apparatus includes a curved lens and a beam splitter attached to the curved lens for splitting an incident light beam into a number of light beams. The apparatus may also include a coupling holographic optical element (HOE) attached to the curved lens to divert the number of light beams to a holographic coupling angle. The apparatus may also include a pair of waveguide HOEs to reflect the number of light beams within the curved lens. The apparatus may also include a decoupling HOE to divert the number of light beams from a holographic coupling angle out of the curved lens.
