Abstract
A near-eye display system includes an image former and first and second series of mutually parallel beamsplitters. The image former is configured to form a display image and to release the display image through an exit pupil. The first series of mutually parallel beamsplitters is arranged to receive the display image from the image former. The second series of mutually parallel beamsplitters is arranged to receive the display image from the first series of beamsplitters, and to release the display image through an exit pupil longer and wider than that of the image former. The second series of beamsplitters has a different alignment and a different orientation than the first series of beamsplitters.
