Abstract:
Various embodiments of the present invention are directed to negative refractive index-based holograms that can be electronically controlled and dynamically reconfigured to generate one or more color three-dimensional holographic images. In one aspect, a hologram comprises a phase-control layer having a plurality of phase modulation elements. The phase-modulation elements are configured with a negative effective refractive index and selectively transmit wavelengths associated with one of three primary color wavelength. The hologram also includes an intensity-control layer including a plurality of intensity-control elements. One or more color three-dimensional images can be produced by electronically addressing the phase-modulation elements and intensity-control elements in order to phase shift and control the intensity of light transmitted through the hologram. A method for generating a color holographic image using the hologram is also provided, as is a system for generating a color holographic image.
