Title: OPTICAL COMBINER APPARATUS
Abstract:
Optical combiners are provided. The optical combiner may have a see through optically transparent substrate (105, 205) and a patterned region (107) included in the optically transparent substrate (105, 205) and disposed along a wave propagation axis (106) of the substrate. The patterned region (107) may be partially optically reflective and partially optically transparent (105, 205). The patterned region (107) may comprise a plurality of optically transparent regions (109) of the optically transparent substrate and a plurality of optically reflective regions (108) inclined relative to the optical transparent substrate wave propagation axis (106). Augmented reality optical apparatus, such a head up display, may include the optical combiner.
