Optical combiners are provided. The optical combiner may have a see through optically transparent substrate and a patterned region included in the optically transparent substrate and disposed along a wave propagation axis of the substrate. The patterned region may be partially optically reflective and partially optically transparent. The patterned region may comprise a plurality of optically transparent regions of the optically transparent substrate and a plurality of optically reflective regions inclined relative to the optical transparent substrate wave propagation axis. Augmented reality optical apparatus, such a head up display, may include the optical combiner.

Optical combiner apparatus

An optical device includes a range of angularly selective reflectors are contained within an optical waveguide substrate and substantially optimized according to their reflector order within the sequence of reflectors. This configuration of reflectors ensures that the required angular information is passed through to the correct reflector within the sequence. The angular response in addition reduces or eliminates formation of secondary images carried to successive reflectors, resulting in undesired artefacts.
