Abstract
Disclosed herein are devices and methods to provide a display including a projection system and a removable lenses including a holographic optical element to receive light and reflect the light to an exit pupil. Each of the removable lenses may comprise a holographic optical element in a different position of the lens to change the position of the exit pupil. The projection system may project an image onto the holographic optical element to project the image to the exit pupil.

11. A system for projecting an image, the system comprising:
-
a frame to removably receive a first one of a plurality of projection surfaces, each of the plurality of projection surfaces comprising a holographic optical element (HOE) in a location; and a projection system coupled to the frame, the projection system comprising; a projector to project light onto a first one of the plurality of projection surfaces; and a controller to send a control signal to the projector to cause the projector to project an image in the location of the HOE of the first one of the projection surfaces. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)

29. A method of manufacturing a projection surface, the method comprising:
-
providing a projection surface material; interfering a reference beam and one or more object beams at the projection surface to form a holographic optical element (HOE), the HOE to reflect incident light to a first exit pupil; and moving at least one of the reference beam, the one or more object beams, or the projection surface to change the HOE to reflect incident light to a second exit pupil different than the first exit pupil. - View Dependent Claims (30, 31, 32, 33)
