Abstract: Point to point transmission holograms are used to provide a scene camera for an augmented reality glasses display system. A glass or plastic substrate acts as spectacle style lens. A holographic medium is applied to a surface of the substrate, within which is recorded a series of point to point transmission holograms. The construction points of the holograms are arranged at the eye and at the pupil of a camera placed, ideally, to the temple side of the user's eye. The recorded transmission holograms act by diffracting a portion of the light from the scene surrounding the user that is heading for the user's eye towards the scene camera. The hologram efficiency is balanced so that the user is still able to see the surrounding scene. The perspective of the view seen by the scene camera is substantially identical to that seen by the user through the lens.
