Abstract
A display device includes an image source, a holographic relay, and a holographic image combiner in an off-axis configuration. The holographic relay may include a pair of freeform holographic reflectors relaying light of the image source to an intermediate image plane. The holographic image combiner receives and redirects the relayed light from the holographic relay, forming an image in angular domain at an eyebox of the display device, the image in angular domain corresponding to the image in linear domain generated by the image source.
