(Phys.org) —Holograms have attracted wide attention for their ability to produce a realistic 3D image of an object by recording the object's light field and later reconstructing the light field on a 2D surface. Now researchers have fabricated a hologram using metamaterials that can produce dual holographic images of different colors on a single surface. The two images are generated by two orthogonal polarizations, while the colors are produced by the hologram's wide operation wave length range.
