3D, true color photorefractive hologram

In this paper, we describe the storage and retrieval of three-dimensional (3D), true color holograms in a photorefractive crystal. The 3D image reproduces the actual colors of the object. The 3D hologram is visible over a wide perspective as demonstrated by moving one's head back and forth while viewing the hologram. The wide field-of-view of the hologram is also demonstrated using an imaging lens with a color CCD camera mounted on a goniometer to record various perspectives.
