摘要: Disclosed herein is a lens for a wearable projection system. The lens includes a holographic optical element embedded within the lens and covering a portion of the viewable area of the lens. The lens can be manufactured by filling a cavity in a lens blank with a photosensitive material and exposing the photosensitive material to a number of light beams to form the HOE.

摘要: 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.
