Abstract
Hologram recording devices and techniques can be employed to produce wide field-of-view holograms. A lens can be used to couple an object beam into a holographic recording material without substantially changing the angle of incidence of the object beam. When displayed, images from holograms recorded using this technique can have a field-of-view greater than that of the object beam. One or more aspheric reflective surfaces can be used to couple an object beam into a holographic recording material at relatively steep angles.
