An optical system for a wearable heads-up display includes an image projector configured to project an image towards an eye of a user and a combiner element positioned in a field of view of the user and in an optical path between the image projector and the eye of the user. The combiner element is configured to replicate the image onto a plurality of positions in a plane at the eye of the user. The combiner element includes a splitting element configured to split incident light into a plurality of directions and a first volume phase holographic (VPH) element. The first VPH element includes a plurality of multiplexed holograms, each hologram configured to selectively collimate incident light according to a respective angle of incidence on the first VPH element.
